If you do start consuming them like crazy, you need camber plates. Or you need an instructor to slow you down
Biggest thing for intermediate students is to keep getting instructors in the car. Find the CDI and tell them you are solo'ed, but want to work on x,y, and z and if they can find somebody to help you out for a session or two. Hell, half the advanced students I usually drive with would benefit with an instructor in the car. I found two seconds late last season by working with a friend instructor in the advanced group.
Never understood why people want to ditch the help ASAP and drive by themselves. But then again, I don't have God given talent.
