Piper Cub
StarBucks my experience relates to the Super Cub (150HP) and my observations may help you a bit. I did my PPL on the PA-18 in the late 80's and have since moved on to Spam Cams but I would still fly one given the chance.
As you will know by now keeping the plane straight on the ground is one of the first challenges. I found that applying a bit of pressure to both rudder pedals at the same time and then adding extra rudder input as required solved my own problems of keeping straight whilst taxying and landing/takeoff.
The climb rate was phenomenal and at some large airports we could have been at circuit height by the end of the runway - of course that needs to be avoided.
On one flight I opened the sliding side window and accidentally knocked the rear throttle control backwards. The subsequent loss of power at 2,000' was a bit of an addrenalin injection! It was resolved by 1,950'.
I am sure that with a bit of time you will enjoy the plane a great deal.
