I have GP 200 box with 19x46 (approx 4.8 final)in my Rapido 230 30mm and JL3 curly and I find it hard work low down, needs a handful to pull off, once it hits 5.5k it pulls like hell, I'm also not small...
At the moment I only have a few miles on it running in so I haven't been thrashing it, but I have feeling it might be better on standard GP200 gearing.
Yours could maybe stand a tooth on the front sprocket if you're currently on 15x46
