I have found that once I fly a jet with a particular turbine, I have almost never have been pleased with a smaller turbine. Had to do a smaller turbine a couple times. After flying with a larger turbine, the only time I was satisfied with a smaller turbine, was in a replacement plane when the bigger turbine caused the plane to just come apart, in the air! (i.e. Sprints just can't handle a P-140 for very long!) The turbine made me do it!
