I am currently shooting a CSS Challenger
39 ATA
29 DL..now with a 28" DL module
65 LBS.
75% Letoff
474.5 gr Easton 2314 Arrows
224 fps
Kinetic: 53.44
Shoot 7 pins...20 yards to 70 yards
Very quiet..very smooth..very accurate

The CSS Challenger was orginally setup for me for a 29 inch "short draw". Due to improvements in my form, I am actually now a 28" DL (28.5" with loop). Due to the shortened DL, I have noticed a lack of "punch" at longer distances (over 40 tards).

I do not want to get hooked on the numbers game, but for large game animals, such as Elk, Kinetic energy min is 50, with a preferred range of 55-65.

Even when I increase to 68 lbs, I still can only increase my kinetic energy to 55.89. I am currently at the low end, and feel that I have "tapped out" my CSS Challenger.

I am looking to add speed, but not at the expense of losing accuracy, smoothness, or quiteness of the CSS, or losing kinetic energy by simply looking at a lighter arrow. I am looking for "punch" at over 40 yards.

Have shot several bows for comparison, under my current setup
Bowtech Patriot..Hoyt XT 1000, Reflex Buckskin, Parker Hunter Mag, and am planning to shoot a Mathews (Ovation..or LX), as well as the new CSS Encore.

I can see from my initial tests, that all of the bows I have tested seem to be able to increase my fps..and KE
Bowtech Patriot.....239 fps..60.83 KE
Hoyt XT 1000...237 fps...59.82 KE
Reflex Buckskin..236 fps...59.32 KE
Parker Hunter Mag...235 fps..58.81

I am anxious to shoot a Mathews, and the new CSS encore..

Under 40 yards, everyting looks good.
Over 40 yards, is difficult to judge which of the bows will provide the "punch" I am looking for. I am also not sure about advantages or disadvantages of single cam, versus a double cam.

Any suggestions would be appreciated.
