I posted last week that i purchased a new Patriot Dually, 30", pulls 74 lbs. Ive been waiting on the 30" mods and they finally came in and we got em installed. First thing we realized was that my Gold Tip 5575 at 27.5" with 125 grain tips are not enouph arrow for this bow. We tried to paper tune and got every kind of tear that there is, low right, high left etc. He handed me a heavyier grade carbon express arrow that 27", he put a 75 gr head on it and it shot bullet holes, so I need new arrows. Any suggestions here? I want to stay fast but I also want to hit em hard. Im thinking a heavy spine arrow in the 475-490 grain range at 27.5". That being said, would I benafit from a lightrer head? I want to use 125's but not if my flight is gonna suffer. Also, it shot 296 fps with a 403 grain arrow. The bow has a string loop, bowtech string dampners, and a served in peep. Also has like some kind of eliminator buttons on it? There are two both under the string loop and definitley installed by bowtech. Do I need these or can I cut em off? Does that speed sound about right? Also, i noticed every Bowtech in the shop had cable dampeners(look identical to the string dampners). But my bow didnt have em. I asked him about it and he said he dont know maybe it was cause you have a dual cam bow and all those bowtechs are single cam. Said he would contact Bowtech and find out, but I know better. Should I have the cable dampners? Thanks for your help
