This is true, but I do know that my leg strength lags behind my aerobic capacity quite a bit. I think some of these climbing specific exercises (and some from the Training subforum) will help to address muscle recruitment in ways that more general training won't. Yes, I totally need to work on everything, but knowing that steep long hills are for sure in my future, I might as well prepare a bit for those.
10 - 12 hours a week with a focus on climbing should do a bit toward helping me with the hills and addressing my general fitness as well, I would hope. All in all, looks like I will be taking this coming season more seriously, which can only be a good thing.
Thanks everyone!
