It's not much of an issue in the BOB setups, where both the hurricane 1 and 110c4 dominate the historically superior spit1 and 109e.
As for the 110c-4, it's no more of a problem than most of the planeset. The extra few hp (20?) don't help it that much. Even if we had the lesser HP version it would still be faster than hurrican1 and spit1, so the end result would be the same.
I wouldn't mind the 110 being redone, though, if only to get the flight model upgraded to higher quality standards.
EDIT: I'd hate to have to redo all my skins though, lmbo!
