Im getting ready for the season and need new arrows. Ive got 10 GT Prohunters 5575.

I need to get new arrows for the season... If I get GT XT hunters 5575 will I notice a difference? Will my bow need to be retuned? I know it might need resighting....

Im leaning towards just paying some more and getting the pro's but I could get 2 doz. XT hunters for the price of 1 doz. pros...

Decisions, decisions.
