SInce you're level 88 I'm inclined to say go for the R11 driver and Burner 2 irons. You may find the irons a bit quicker than you're used to so the L59 G10 irons are another option, fine clubs that will still work when you're a legend. There's also a higher level G10 driver.
The Burners do seem to have their quirks though, sometimes missing the ding very slightly will send the ball way off line or leave you way short of the target. This seems to be due to the spin they generate, playing with Callaway S balls means a mis-hit will be severely punished. If you use something with less spin they seem more forgiving.
My personal experience is that they really do have good and bad days, I use the same ball for all tournaments and sometimes the irons are great, other times they land the ball 30 yards short. When they work well they're brilliant, you can hit a 3 iron 210 yards onto a green and the ball will stop quickly, no other irons will do that for you.
You'll likely get lots of different advice, all well intended, but at the end of the day what works for me or someone else may not be right for you. If you have the credits rent first but play as many rounds as you can to get a feel for the clubs.
