Somethin Extra!
I built a Sig Somethin Extra while "Wringing out my trainer". This worked out great for me.
I also think that one should take in account the nimbleness of the trainer that they learned on. For instance, if you learn on an RCM trainer (Flat bottom wing) as opposed to a semi symetrical wing (such as the Avistar), You may want to lean towards a more docile second plane.
Just my hay penny.
