Hi all,

I changed my clubs to 710 MB/CB combo a couple of years ago and got fitted for x100 shafts, my old clubs 990's have s300's in them. I want to put x100's in the 990s to use as practice clubs (I have them with me in London where I live and work but the 710s live back home in wales where I actually play), will this be a problem or not? I wasn't sure if the head weight might not be correct? Or are they the same for s and x flex?

Any help would be really appreciated,

best,

Dan
