There have been a couple of people who have answered this, but I was hoping to get a few more opinions:
I've been using Taylormade Burner 2.0 (L76+) for quite a while. I've always wanted my clubs to have matching meters, but that wasn't really feasible until the Bladez came out. I have the level for the R11s, so I'm left with the dilemma:
I'm used to the increments of the Burners/Bladez, so it wouldn't require a change in my game, and I would have matching meters. But, apart from the meter, the R11s are objectively better clubs.
I typically use low level Callaway balls, and can't afford both an upgrade of clubs and an upgrade in quality of balls. So, stand pat, Bladez, or R11s?
