I started with some LM All American Jr. 6 Lens Set (same as All American, but not spring hinged). They worked really well, but they were a size too small. But, when I went up to Sparta for the AIM Nationals, I got the frame swapped out no problem and they even cut me new lenses. Now, they fit well and work great. I like how they wrap around your face as well.
Also, the All American Jrs are really cheap if you don't mind them not being spring hinged. A Randolph Classic 1 lens set is $160. An All American Jr 3 lens set is $150, so for $10 less, you can get 2 more lenses.
So, in all, the All American or All American Jr, should work fine.
