I think the ability to attempt correct takeoffs and not tip over on the inboard wingtip greatly outweighs the the value of saving an ounce, particularly on an airplane with the (pretty decent) Flite Streak wing. The Skyray wing is nearly identical aside from lacking the "fixed flaps" and it will fly pretty well even at the kit weight of about 36 ounces, as long as you have a good engine. Almost all of the local Flite Streaks have conventional 2-wheel gear. And, there's no reason to make it weigh more. I think the cut-in-half-and-rebent Hallco gear on the Skyray, plus the new spoked wheels, weighs less than the single-wheel gear that came with it.
For a Ringmaster I might have another opinion, but even then, one of the best-flying Ringmasters I have ever flown was a stock kit-wood version with a full, opaque dope finish, that probably weighed around 30 ounces - with a 15FP.
