Your IBO speed is 295 with 30"draw and 350grain arrow.IF your arrow is 29"s long your arrow weight is around 457grains. Thans 157grains above IBO, that alone would put your speed down to 220fps, not to mention all the stuff you have on ur string. So at 240fps your getting 58lbs of KE.If you went with say a Maxima 350 arrow at 29' length , your looking at about 387grain arrow weight, you can expect speeds around 270-278 and 65lbs of KE. So who ever told you that you needed an arrow that was that heavy doesnt understand that when you increase arrow weight, you dont neccesarily gain KE, because you loose so much speed. You just have to find a happy medium. Hope this helps..
