I'm in the mountains near the high desert, don't float fly, and my plane is hangared, so the wood up against the gear leg concern is no big deal.
The thing I remember about the Wainfan treatise on TE drag reduction, was that unless you go all out and actually achieve the lowest drag fairing,(the one that is most often simply too impractical to fab and put into use, and too fragile, but damn it has the least drag) you are better off going with that blunt shape then a more common sharp brake formed TE. Counter intuitive, but then I thought about the 3/8" round tube that makes up my (RANS S_7) TE on the flaps and ailerons, NOT sharp brake formed, and how I easily dead stick ridge soar even with 29" Airstreaks (there, I got to work that in again....) I got to mention this subject to Randy Schlitter, the RANS designer. I asked him if the blunt TE was just a form follows function thing or if he was aware of the benefits, he was all over it, knew about I mean, not accidental in other words, it just turned out to also be the easiest way to make that TE. Less work and less parts count AND least drag.
The other thing Wanfain says was the lesser need to address the LE with a streamlined shape, at least at Cub speeds, as compared to the TE, the TE being the one that pays off more. Sure can't hurt to do the LE though, looks good too.
