    Just wanted to know what you FOC is on your arrows and how much kinetic energy your arrows have? Hunting arrows of course

    I think momentum is more important. I check my numbers and get back

    LOL. One thing I do like about PSE is the power they have. Their bows are very easy to shoot for me as well.

    I shoot a light arrow in GPI so I can get high FOC and make up my weight

    My arrows are fairly light right now at 380gr. My weight up front is only around 120. I'm going heavier this year though.

    What's your total arrow weight?

    Thats all.:p

    I have 75 gr brass inserts and 150 gr heads and that puts me in around 19.5 % foc. These arrows have factory wraps or the foc would be higher.

    My ke is around 56 ft lb if I remember correctly because I'm only shootibg 57# @ 28"

    Wow that's heavy. I want to go heavier but do you think it would weaken my spine too much?

    I think I am borderline on spine anyway so I may move up to a 340/330 spine

    I shoot mechanicals and haven't had an issue. I am going to go up in weight to around 420 though.

    You would have to be on the real light side of spine before adding weight to the front will be an issue.
