I have been going back and forth on this issue using my HHA slider or the 5 pin fixed sight for my Pulse. The Pulse is strictly a hunting rig. This season I got busted when changing my slider to 40 yards from 20 but I like the fact that I can set the pin at 25 and not having to go in between the pins.
On the other hand I do like the fact that there is less movement not having to set the yarded with a fixed pin sight. One idea I had was to set my set pins at 20,25,30 etc and only go out to 40 since I probably wont shoot past 40.
