When PSE unveiled their X-Force line of bows in 2007 they took the archery industry by surprise.  At the time they had done what others had only dreamed of.  They produced a bow with a healthy brace height, light mass weight and smooth draw. That may sound fairly status quo for many bows on the market until you see that it shoots at an IBO rated 350 fps.   A bow with specs like that is definitely worth taking a look at.  The best part is the for 2009 PSE has out done themselves again

For 2009, PSE has revamped and improved an already very impressive bow.  They offer an X-force for virtually all archers with six different axle to axle lengths and brace height combinations.  PSE has designed a new cam called the GX hybrid which is allowing them to increase the speed of their bows as well as increase the let-off.  The two main bows are the X-Force GX and the X-Force Dream Season GX.  The GX is 32.5” ATA with a modest 6” brace height.  The speed and let-off of the new GX is where all the changes took place.  The let-off went from 75% to 80% and the speed crept up from 350 to 352 IBO.

In the Dream Season model which has an ATA of 32.5” and a 7” brace height the changes were about the same.  The let-off went to 80% and the IBO speed went up to 342.  They also offer all of their X-force bows in the new Mossy Oak Treestand camo as well as the digital camo. 

With all the changes to the 2009 X-Force line, the bow still shoots as shock free, light, and quiet as any bow on the market.  Where it gets ahead of the pack is in the speed department.  With all of these features it will make it a very good choice for your next tree stand companion.   

In the internet, we may have some chances to get many kinds of info that we need for many kinds of purposes. Some of us use the internet to search for some info about the health. Some of us may search for some info about the health treatment. Some others prefer to search for some info about the fitness exercises and equipment. As we all knew, there have been so many kinds of technology developments that may help us on that.

Today, we may have some chances to get some information about some fitness exercises that related to the back pain. Some of us may have some kinds of back pains soon after we did some exercises such as the sit up or many others. In the internet, we may get some info about some devices that we may use to reduce the back pain after we did some exercises. The device is called as the Back Revolution that would be useful for the back therapy.

We may use the device to have the therapy for our back pain that called as the inversion therapy. Click the site above and read about this device before you decided to buy it.

After reading countless positive experiences from people who have used Rage broadheads, I decided to give them a try this season and have been thoroughly impressed so far.

 Upon receiving the two packages I ordered, I installed the practice tip that is included with each pack of heads. The arrow flew perfectly with my field tips at distances out to forty yards. The practice heads look the same as the real heads themselves but the blades don’t open up which ensures easy removal from your target. I was shooting into a bag target and the heads were easy pulled out after shooting. I would be hesitant to use the practice heads in a 3-d or foam target for fear they would really take some chunks out of it and decrease it life of use.

 I weighed the heads to check for grain consistency and found them to be all relatively close. The range between the heaviest and lightest of the 6 heads was only 1.9 grains. These blades are easily locked into the place when the blades fold back and click into the rubber o-rings that come with them. The buyer is also supplied with 3 replacement o-rings.

My first experience with the real head was this past week when a couple does traveled into an oak ridge. Both shots were at distances of around 30 yards. The first doe was shot slightly quartering away and the second was perfectly broadside. Neither traveled far and left remarkable blood trails that made for easy tracking even in the dim light of the overcast morning. Upon recovery of the arrows, the blades were all still intact and could probably be re-sharpened for further use, but Rage now offers replacement blades for their heads. The blood trails started within 5 yards of the location of the shot. It looked as though someone took a glass of red paint and threw it down the trail. I’ve seen great blood trails in the past from archery kills, but these topped them all.

The entry and exit holes that the 2 blade Rage created were very impressive. With a cutting diameter of 2.5 inches, there were two huge holes in both deer. In the first doe, both lungs were completely gone, and the second one nearly had her heart cut in two. Neither shot was affected by the ribs when it entered the deer. Due to the design of the head, a hunter must be conscious of shot placement. Hitting the shoulder bone would greatly decrease penetration, but that is an issue with nearly every head on the market. Both shots easily passed through coming from a 63 lbs. Switchback and 380 grain arrow. I’m excited to see the next wound these heads create!
