I'm not a legend neither but a TM with low average.
I just played legend friend of mine using the R11 driver, I do have the R9 for 280 yards..... let me put it this way; I normally drive longer then the legends for about 20-25 yards (tee difference), this time, I was driving longer then my friend for just about 5-8 yards hitting the "ding" both, using both, the callas Z.
Great tool for the legends...those 15-22 "effective" yards more will give them big chances to get the second shot closer to the pin, simple!
Wish I could get it now, tho I'm only level 85.
What I do hate of all this is the "trading" price when selling & buying clubs, so blody greedy giving you 10 percent of the tool price when selling it back to WTG in order to get new credits. I was born in USA myself, although this is too american to me.
Well.....take it or leave it. LOL
