straight arrow, I am pulling more than 7 grains per inch and my arrows are flying great. I am hitting a coke can bottom per say out to 40 yards consistently.
7 grains per inch is a pretty light arrow. 7 grains per pound would be a much better choice for most people. I'm not saying that you aren't hitting where you're aiming. It has been proven time and time again that a very poor flying arrow can hit the same spot each time. Your arrow may be flying perfectly, but you won't know just because it's hitting where you're aiming.
I just found it amazing that adding the 35 grains to my arrow, jumped my KE by 2.3.
That's a 5% increase in K.E. I doubt that will be noticable in the field.
we all tune our bows for perfection, I didn't think that tuning an arrow to perform the best was a bad idea?
Personally, I've seen very few hunters who actually tune their bow for perfection. Most of the ones I've observed do a very half-baked job. I do agree that it's a good idea to try to get your arrow to perform it's best. I just have a different definition of what is best. I don't think tuning for speed or KE is best. I think arrows should be tuned for the best possible flight. This can be done on many medium weight arrows and lots of heavy weight arrows, but is much more difficult on very light weight arrows shooting fixed blade broadheads.
