I typically have an easier job paper tuning with feathers, they increase FOC and make an overall lighter arrow.
Blazers are water proof, quieter in flight and if you accidently touch them.
Most of the time I hunt from a blind with the bow laid across my lap; frequently my sleeve will brush a feather making a noticeable noise. Also, since the shot is at ground level I’m shooting straight through the deer and the arrow may go 15 yards or so past where the deer was standing, so I think a wrap will aid arrow recovery; therefore, I’m currently using Blazers with a wrap.
I do think feathers 4” and longer offer more drag / control than Blazers and that might make a difference if you have trouble getting fixed heads to fly.
I started out unting with feathers but here in Oregon it is wet alot second season. Too much problems if your feathers get wet. Blazers fly a broadhead so well-I will probably never shoot anything else
