I have the 1.5" for target/3D and 2.25" for hunting (new this year for me). The 1.3" seem to work well for me. I'm not the super competitive type and I shoot in the middle of the group as far as scores are concerned. Like I've said before the equipment you use should please you (you alone). Most of the "middle guys" are successful on their hunts. Does that make the equipment they use better than the others? I think not. I think your confidence in your equipment along with a spot of luck makes you successful in all respects. You should try what you want and make your decisions based off your own experience.
