I forgot to add though I think the serve is pretty good at the moment so I don't think any major changes are needed, my post maybe gave the wrong impression...lol I'm definitely in favor of less confusing updates and more stability.
I for one am fine with the second serve how it is. I go for my second serves a lot and I get lots of DFs some matches but others not as many which is realistic. Soderling sometimes has like 105MPH+ second serves and he never DFs that often. It is possible to have big second serves.
