If you can work out the weight and balance and make sure you're below max gross for each flight (and you don't live in the mountains or the south...), I say go for the 150/152. I did my entire private in 150's and 152's and loved it! Yeah, no fantanstic climb rates, and stalls were pretty much nothing....but it still did the job! I guess I weighed....well, I was about 185 then (get out of the Marine Corps and it's so hard to make myself go run!!!), and my CFI was a good 210. So, depending on the radios in the aircraft....it's possible.
The best part about it : After I was done, I got checked out in a 172 in .7 on the hobbs, and I might as well have been flying a Learjet!!!
