RE: broadhead tuning question
When you see something like this, you don't want to move the rest opposite the BH's but a lot of the times move towards where the BH's are hitting.
I do this with Bareshaft. So if your bareshaft is hitting 6" to the right, move your rest to the right. If you have to move more than 1/8" past bow center, you need to look into some different spined shafts.
According to OnTarget, your a tad weak spined with that combo. Like I said, I would not move more than 1/8". I would tune the bow to the arrow. Drop down to 64lbs and see what happens.
