He was right about the big ring, but I guess it all depends on your style and where' you're comfortable. I spent the whole race on sunday in the big ring and every time I looked down at my computer (which wasn't too often I admit) the rpms were 100 or so. I'm just comfortable there and find that when I need to shift to a higher gear, it's smoother and easier on the legs than when I shift up from a lower rpm. For me, anyway, it's easier to get a "snap" when I'm spinning at around 100. I think I need to work on using a higher gear and lower rpms when doing some hills though as I have a tendency to exhaust myself frantically spinning at 100+ up hills when I could power up the smaller ones instead - I never seem to ever get out of the saddle, which on the short hills in crits is probably hurting me.
