The problem isn't the size of the case, more room wouldn't give much advantage. To self wind, the tape has to slide over itself in all the numerous turns, as the leaf spring does too. If you get some grit, rust, mud, water... the friction is greatly enhanced and the spring can't deliver enough force to roll back the tape.
A manual crank on the case instead of the spring (or have both) works way better in the dirty places, but sure, it's annoying.
The wind was way stronger than announced today. It screamed between the limbs this afternoon. It broke more stuff than the 3 storms two weeks ago. I was in a twin skinny dead maple and I just had the time to cut the tops, before the serious hit. It was in a very small valley and luckily the air flow passed a few meters over me, rocking the crown of a big oak behind/over my head.
It allowed our fire to eat a lot of contaminated wood though, even the logs rotten and deeply soaked by the rain.
