Thanks for input. I shouldn't post in the heat of the moment. I'm just frustrated and discouraged, but it's alright. I'm down off the ledge and ready to go for a ride again. Shredded bar tape is just another chance to try something new, right?

Still bummed about my bibs, but it could be worse. Maybe some bad luck, maybe not, but I'm none the worse for wear.
I don't think your fall rate is that unusual.
I've been practicing cornering a lot. The physics of it makes sense as far as leaning/counter steering, and I've been working on picking and holding steady lines, working on my balance, working on apexing, working on countersteering/leaning etc.
This sounds like you might be pushing the envelope a bit too hard, too soon.
But I clearly need more practice at it, so that's what I'll do. Thinking about it more, it very well could've been the painted lane stripe on the bike path there, I slid right as I was apexing in a left-hand turn, and I may have touched that line while apexing. Or, I just plain messed up and I need to keep practicing. Or both.
This sounds like it could be a consequence of not enough experience.
