Is taking it back for an exchange an option?
My thoughts exactly. You didn't spend a hundred buck to get fliers. I'd Take that arrow back to the shop and if they can't remedy the issue I'd call carbon express directly. For the price of those shafts they should
ALL be perfect IMO. I'd expect nothing less.
If you bought cheap shafts then you can expect that some will wobble but not with the selects. You paid for quality and quality should be delivered. I wish you the best of luck
