Using expo really isn't cheating. It's a smart tool to use.

If you've never used it (as it sounds) then don't just slap a number in and mush on. It's really most useful on the elevator. Small, accurate use of the elevator matters on landing and you'll have the best chance to see what it does for you there. Pick a number like 20 or 30 and fly it until you're comfortable and have actually felt what it's doing for you. Until then, leave it off your ailerons and rudder. When you've got a handle on it, try it on your ailerons and you'll have a better chance of setting it where you need it.
