I have the level 93 R1 and was fortunate to purchase it last year when it first appeared. To be honest it has its good and bad days!
During the last free rental weekend, i tried the R11s which was where i was heading before the R1 appeared, its got a higher trajectory and a slightly faster meter but i liked it.
There is also the X-hot and the SLDR, i rented those as well and was impressed by the latter.
I play regularly with guys in my CC who have all of the above mentioned drivers and find myself sometimes outdriven even when i hit the 'ding'
Dont become another one obsessed with the level 93 R1, there are others that are just as good.
