Feedback? You've got a lot of good suggestions there. Unfortunately, as much as I think that a lot of what you typed makes sense, I also recognize that most of it is waaaaay too radical for Texas Region to adopt.
Don't get me wrong - I think you've got some really good suggestions. But the stuff oyu suggested will never happen at the Regional level in SCCA Solo, because that's not how it's done at the higher levels. I'm not suggesting that it isn't how it should be - just that change of that magnitude would have to start at the National level and trickle down through the SCCA.
That's not to say that it wouldn't be a bad idea if someone were to start an alternate autocrossing series...
