the airfoil on the sledge is tapered from the root to tip , but starts out the same thicknees as the omp. the omp just has a tapered trailing edge.
as for snap rolls i like the way the omp snaps, it like a funfly. the sledge is more of a precision flying machine. i like them wild like the omp.
as for a first kit to build they don't get much easier than a profile to build in my opinion. they are both easy to build!!!
