Yeah, AJ, I too did a bunch of OTS work yesterday, just to see what works and what doesn't. I tooled over to a short (0.15 mile) 6% hill and did it a bunch of times (8), trying to be aware of what I was doing and what worked better than others. I'm ok with the bike swaying a little bit, but I also tried to allow it to swing a little more, as I've seen some people do and also the pros when they are zipping up mountains. Big swinging isn't for me - it feels inefficient and it can throw off my timing. A little swaying seems to be OK, but I think the bike is pretty stationary when I"m in my groove.
I tried the two-fingers on the hoods position and I like that a lot. It's not so different from what I was doing before, but it does keep my weight balanced about right. I also tried different gearing and found that, at least for short hills, I"ve probably been using smaller gear ratios than optimum. I found the best results were 50/19 or 50/21. I probably couldn't stay in those gears for a much longer hill of that grade, of course.
