Ken you are discovering what I have been trying to teach guys for years. Most of what you will accept for sport flying simply won't cut it for precision flying. Granted the airplanes you are flying have built in issues that can't be changed however a good trim will help considerably starting with CG. If they take more then just a touch of forward stick to maintain level inverted flight then you are just too nose heavy. When trimming you MUST always start with CG as it influences everything. Next move on to thrust line adjustments. Just these two things will make the sequence much easier. You are on the road to finding out why guys who want to be competitive in pattern are spending so much money on their airplanes. Pilot skill is a huge factor but will only take you so far, you need the correct tool for the job but that tool has to be adjusted correctly as well. Not saying you won't have a great time flying what you have in sportsman, just that you will enjoy it more if your airplanes are trimmed to their full potential.
