alright some of you may have seen my post on recommendations on bows, now i want to open up the discussion for sights. I'm buying my new bow in the next couple of weeks, ive got it narrowed down to the hoyt faktor 34 or pse source. now the sights im looking at are the tru glo tsx and the IQ bowsight. Now i dont know much at all about the IQ. has anyone shot one before? and are they were the extra 50 bucks?
