I've been running the wrapped Spot Hogg Hunter 7-pin now for the past several years. It's simple, it's functional, and it's durable. It's been through a lot of abuse and tough conditions and I've never had to adjust it after it was set. I did break my 70 yard pin last year during the season, but that's an easy fix. My bow slid down a scree slope about 50 yards a few years ago, and everything was fine.....the bow, the sight, the rest, the quiver, and arrows. That's what I set my bows up for.....durability......and performance.
No they don't. The best long range groups I've ever shot was with .029" pins. Pin float also shows up more with smaller pins.
As you can see...opinions vary. I used to have all 29s (thought I was the only one) but the 50 & 60 yard pins completely covered up the center circle of the target.
