I should mention too, that we also shot the Switchback XT, the Switchback, and a older 2002 Mathews Legacy for comparison. All were 30" draws and we set them allto 70-71 pounds, just like the drenalin. The Legacy and the Switchback XT were with in 2 feet of each other. The Legacy clocked in at 287-288, the XT was hitting the 290-291 mark, and the shocker was the origional 05 Switchback (my personal bow) was only 2 f/s faster than that. It was comming in at 293-294. I was hoping for better seeing that on paper its suppose to be 318 IBO and the Drenalin is 320 IBO. But whats on paper and whats real is two different things, which I already knew. I also know that you can have the 4 brand new bows of the same modles set them all to the same poundage and have four different reading in speed. So that said for fun of it I am going to compare my Swithcback and my Switchback XT. Ilike my 05 Swithback so much that I hunted with it again this past year.The XT on the other hand I have hardly shot, I bet I haven't put 200 arrows through it. I got it paper tuned at 70 pounds, turned it down to 62 poundsand thats about it. It sat there in its casethis last seaonswaitingto be used as a back up bow as planned.Not saying I don't like it because I do, when I do sit in some blinds in the furture, come antelope season and such I will use it for the simple reason its only 31" ATA overallthats small and handy so it shouldbe very nice to use in a blind. Anyway getting back on subject, next week I am going to compare my Switchback XT, to another Switchback with the same 404 grain arrow just to see the actual numbers.
