What exactly are you losing at the bottom end?
There is rarely ever a time that i say to myself "boy if only i had my _____ wedge with me". There is almost always some shot I can use to get it close from the hole from inside of 100 yards. The same cannot be said from 210+ yards. Fwiw, i've had a gap from 90 - 115 yards for the last 5 months, and havent seen my results suffer too much.
edit - I see you are still using taylor made irons for some reason. That makes it somewhat more reasonable to use 4 wedges. I cannot for the life of me figure out why you'd use those irons though still. They are simply inferior, not a matter of personal preference. You will refute saying 'g10s get blown around in the wind' well guess what, don't use full backspin you can manipulate the exact same trajectory as the TM's, with more precision.
Bottom line is G10 irons effectively give you 9.5 clubs vs 9 with the taylor mades, the 115-210 yards spread instead of 122-210 just gives you 7 more yards that you don't need to cover with additional wedges.
