Been a few things in the past year that have made me competitive in in RG's...a completed set of Cleve wedges and the R1 driver.
Jury is still out on the level 97? Putter I tossed 3K credits for and ditched my Rossa.
I think the extra few yards here and there that any driver will afford, is most evident in MP, not in SP...reason I say this is it can get tiredsome/irksome hitting first on your approach shot...just a mental thing IMO.
I never tried the BB...but it's almost hard not to hit the FW with the R1.
