Currently fly a C152 but the plan is to swap to a PA28 prior to Nav otherwise we will never get there!
What's your issue with the 152 - speed or fuel capacity limited by weight?
Lots of people have done all their training on a 152 ... but it was easier in the days when people were less concerned about the strict legality of taking the things off the ground with a decent amount of fuel in them. Or perhaps we were all thinner then.
