Stalker 22,

That's great about the new owners. A good pro shop is a wonderfull thing. It's almost like having an auto mechanic or doctor that you can trust.

One thing that you might ask them about is your arrows. The 5575 is usually underspined for your set-up. The bad news is that an arrow with enough spine is often heavier and slower than the 5575's.

Good luck
Allen
