Thats a great review. I hate Nike sh*te, but almost makes me wanna go find one and try it. Remember that in general the R7 is a pretty low spin head and thus fairly short in carry for most of us.
I have got a Harmon Tour Design shaft in my 3W and i must say it is a superb shaft, which I would choose over any of the Adila range. Even got my pro to frequency match it and it feels great with any shot off the club face.
