I would go with anything over the OS VG with the ABL sleeve. Check out this thread.

Never owned a VG but not big on nickel plated sleeves!
I have one STS D21B with well over 5 gallons on it still running great with the stock carb. I have a STS 28 in my Savage stock carb but only have about 1-½ gallons on it as I have been to busy racing my Hyper 8. Then I have a STS D21T MKII that I am going to run the beginning of next session still in the box.
