I don't go so far as leaving the rain jacket behind. Once rainy season starts (and I'm in Portland, OR, so there are only a few dry months) I always keep a jacket with me. I just don't use it that often. I see people wearing them commuting in the summer-I'd get soaked if I did that.
I'd rather keep at the pace I want to ride rather than slow down so I don't overheat. I don't ride that hard, either, but I do tend to sweat a lot.
Have you tried the new high end stuff such as Gore Active? I used to think like you but now with the active jacket I have I almost would like to use it as my primary shell. It's just that good.
