By "hard to pedal"- are you referring to small cogs or the big ones?
I don't know my terminology - it's so hard to explain in words!

By hard to pedal, I mean the smallest gears on the back wheel. So I guess my biggest problem is when I'm on my small chain ring and my smaller gears on the back. And my secondary problem is when I'm on my middle chain ring and the smallest gears on the back. Which I guess means that the problem is when I start cross chaining. Although I think maybe it's cross chaining way before it should be?

Starfish - I'll ask my LBS about trim. I hope I have this option. But I won't try it myself...I'm sure I'd mess it up even worse than it is now!
