If you can afford a new rear hub, flipping your drive train would still be your best bet. I ran RHD and grind right, went through SOOO many sprockets this way. I tried using micro sprockets (22-23t) and still killed em. I never used a bashguard sprocket, BUT, i believe if you did, the guard would catch on double pegs and such while youre learning how to do them.
I finally switched to LHD and used a non-guard sprocket and it lasted me about a year, I rarely hit it. Usually only when I got into a feeble crooked and my rear peg slipped off.
If you plan to learn oppo grinds/crooks/crank arm grinds/sprocket stalls, then definitely go with the guarded sprocket. If not, and you can get a LHD hub in the near future, definitely get the Tree, and you can buy a separate bashguard for it later if you decide to learn those other grinds.
