Picked up a Proline Mountain CP3 (2004-5) New old stock off AT, the bow is all Darton, I wasn’t sure what I was getting but I knew it had CPS cam 1/2 which I have always loved. The Bow is: Proline Moutain series 7575 machined riaser (no forgings here), darton split limbs (as used on Yukon bows) CPS 6 (express) cam, 35" ata, 6 5/8 BH, draw is smooth,did I say smooth I ment smooth,smooth. Now the Kicker 28" DRAW, 59 LBS. 340 GR Vapor 400, 287FPS!!, 360 GR Gold Tip 55/75 277 FPS!! the same arrows shot 280 fps and 270 with my 28" draw, 60 lbs. Hoyt TurboHawk, when you do the math the IBO on this bow works out to 327-330
