Just to be clear, I ALWAYS round the leading edges of my wings. Wings are beautiful structures and not doing that would feel offensive to me. But the one time I flew a plane without a rounded LE, and then fixed it, I was surprised I couldn't tell the difference when it flew. I'm not saying it would necessarily be true of all types, or under all conditions...I'm reporting what I observed in this one instance. If it meant stripping off the covering and re-covering, on a trainer type, I wouldn't bother. But re-reading the original post, I see that it was not covered at that point, so yes, I agree, round the LE.
