Assuming this is not intended to be your trainer (as others have told you, this is NOT a trainer, but a high wing aerobat), clipped wing is the way to go for most people. With the full wing, these will float forever, to such an extent that landing can be difficult, especially in a breeze (most of us have probably seen a full wing version land backwards on a breezy day). Clipped wings will speed the plane up on approach a tiny bit, make the plane a bit easier to tote around, improve the roll rate and general aerobatic performance.

One other thing to note, Cubs are renowned for their propensity to ground loop. This is when you are either landing or taking off, and for whatever reason, the plane suddenly yaws (turns) 90 or 180 degrees to your intended direction of travel. This can be aleviated or at least lessened by adding a degree or 2 of toe in to the main gear wheels. Just make the gear slightly "pidgeon toed" and it'll rarely ground loop. This works for all tail draggers.
