Sharkey...I put a Keller on my setup last year and would trade back for anything. One comment however, they are not as simple to use as sight it in at 20 yrds and you are good to go. It took a fair amount of small adjusting to get a consistent pattern I was happy with. I am very comfortable shooting out to 35 yrds with mine. Down side is that they aren't worth a dang on the ground. All of my hunting is from portables so it works out ok.
