Have a Horton realtree HD 175. The arrows that have been suggested through Horton are the 2216 alum. with a 100g tip. 4" vanes (which also came with the pkg.) the problem, with that set up there's a 8.5% foc. I'm about to slip a 125 thunderhead on and look at that number but I'm worried it may steer the front. Does anyone have ideas of weighting the front and using an 85 or 100g? hoow can I do that?
