I'm picking up a Jamara F4U Corsair .61-.91

I usually lean toward the larger end of the power spectrum..

What do you recommend in a good 70-90 two-stroke engine?

I know ABC engines well, is there any reason to go ringed?

If TT would sell a .91 2-stroke I'd be all set. I'd prefer not to pay the extra $$ for the O.S.

Magnum XLS-91?
Enya 80?
GMS 76?
Tiger Shark 75?
Irvine 72?

Thanks for your input.
