RE: At-6 for 3rd plane?
I have no idea how Righty could have missed the line "I recently soloed," but I think that you will have no problem with that plane. I could have even been your second plane. Since you are low time, maybe get your instructor to buddy-box with you when you get it just for one flight. Make sure to do at least a few landings on the box before you cut your instructor loose. You should have no problem.
