go lower
i used to run 46x16 which was fun, but then i switched to 46x19 for winter gearing, and i loved it, wasn't even that spinny then I thought. I ride with the Purdue Cycling Club and I can keep up just fine with all road bikes, Especially when those giant hills come, then I can mash up the hill just as fast as roadies
The only downside is the downhill, but i learned to go up to extreme cadences
