I asked this question in a related thread:
I'm maybe 7 weeks to a couple of months away from level 90 and was planning on getting the R11 full set. Now I'm not sure if that's such a good idea, since I'll probably turn right around and sell back the R11 driver in order to get the R11s. Almost seems like a waste of credits, but I don't know how else to do it.
I don't really have a use for a hybrid, so am I better off to buy the R11s driver and R11 3-wood separately, then buy the iron set? In other words, forget about getting the full set?
edit: Did some figuring, and if I get the R11s driver, R11 3-wood, and iron set separately, cost is 6185. Full set (with the regular R11 driver and a hybrid) is 4995, then I could just sell back the driver and the hybrid for what, about 675 credits?
So it looks like the better move is to not get the full set if I'm planning on upgrading the driver.
