I like alot of the ones above another one I enjoy is inside out precision. I really like his because he usually shoots the bows at 2 different draw lengths 28" and 30", and 4 to 5 different arrow weights to give you a great idea on speeds.
I used to have a swaro X5 50mm and it was a great scope, but I sold it and
got a Leupold Mark 5HD 3.6-18X44 and absolutely love it. It is very compact and optically I could tell no difference. I still use swaro NL binos, so I am not anti swaro in the least. lol
I have both the Sandtrap from Hitek Archery and the Titanium Archery Products, they are practically the same, I can't say one out preforms the other. I would get whichever was cheaper, or whichever color you wanted.
I would look for a used PSE that has the S2 cam, it offers excellent performance for short draw folks.
They offered that cam on all their bows until last year, last year it was a custom order only unless it was a target bow. It is only available now for warranty work. If you could find...
