You don't have to spend a lot of $$$ to get a good sight that is very durable and functional. I have a buddy that shoots a different version of the IQ sight with the Retina Lock and it really improved his shot groups especially at 30 yards and beyond. I do not think that you will regret going with that sight and if you really like it you can always upgrade to a different IQ sight. That way you will have a backup sight if you happen to damage one in the middle of the season.
I have the 5 pin and absolutely love it. A guy I work with let me shoot his and I was hooked. Now have 5 pin on both mine and the wifes bows.
