It depends, was your "trainer" a flat bottomed wing, or semi-symmetrical wing. There will be a difference in transition to second planes depending on this.

Also, you mentioned your perception of your flying skills. If you are fairly comfortable with a high wing semi-symetrical plane, then you can consider all of the above options, as well as things like a lanier stinger. If you are flying a high wing with a flat bottom airfoil, you may consider a shoulder wing with a semi-symetrical airfoil.

Anyway, a little background on your trainer and flying skills would help for a better recommendation.
