@BrotherSullivan-I didn't mean to make light of your point. I was just surprised you were thinking that way. You are so close to a great setup with what you have. The iron difference alone between what you have and those G10s will get you places you haven't been yet-like on the green in 2 @BPB5.
You have a good driver, a great 3w and a pretty much useless HB. Trade one of those for another master wedge that goes with the G10s (like the 105 Satin) and you will be bigtime set up. The longer distance of the high irons takes care of HB situations.
Maybe renting the G10s for a day will convince you but that kinda sucks because I know you'll be happy as a clam and you would have wasted the rental fee. A word of caution-the G10 flight is different. Higher loft, more susceptible to wind, able to overcome elevations and way more accuracy. GL
