R9 Irons Vs R9 TP Irons

[morgy]

Can anyone give me advice on which one of these are the go? I'm moving from some Titleist 710 MB's as my ball striking has taken a turn and I need more forgiveness. What are the basic differences?

I have surprisingly found some success moving from a Stiff to Reg shaft in my driver and may look to do the same with irons.

Google the offset, TP's have minimal, R9's have progressive.

Heads on the R9's are larger and the R9 has a .370 tip.
