Yes I used the G10`s for a few months before going to the I15`s.
I would say the Taylor made irons are a slight step up then the G10`s.
The TM iron`s have that little bit extra stopping power. Also the hitting range is different PW starts at 125y , 9 iron 135 yards etc etc.
I do think they are better then the g10`s , but others may like the G10`s over the TM iron`s really a personal thing. Normally I would say If it`s not broken don`t fix it..
more time is needed with them on more causes.
