I might try 1.8 or 1.9. I'm not sure where I stand on the 2u question. Might never have been too much, or might be it was then but isn't now. If it were me, I'd be tempted to try something just shy of 2u for a couple days to see if that is somehow the sweet spot. If not, then you could go up to 2.2 from there. That's just me, and I don't feel clear on Alex's #s, so see what others think.
