So, I was shooting some low profile, Easton 2 1/2 inch vanes and was getting beautiful flight with my broadheads, hitting kill zone easy at 55 yards... I stripped them and put blazers on, thinking the higher and more ridgid vane would be better??

Well, I stepped up to 20 and let a broadhead fly and SOB... the arrow looked like it was having a spaz attack all the way to the target. Obviously getting contact... Why would I be getting contact with them? dont most bows shoot them fine? The guy who had the bow before me shot them...
I'm confused!
