Start your training in winch land and you get hundreds of low altitude releases. You get quite good at climbing out and recognizing the need to give up and enter the pattern. Even better, do winch training when you're a kid and your brain is a sponge.

Train with aerotow, and you take a relatively small number of 3000 foot tows and just enough pattern tows to achieve PTS landing standards. Climb outs from pattern tows are rare. If you have a CFI-G on board, and you might climb out if the lift is solid and easy when you release.

Move on to XC, fly less frequently, land once a day, and see a regression in landing proficiency. Make an effort to maintain landing proficiency.

Having trained with aerotow exclusively, I'll release at 1300 in reliable lift, but if I don't immediately climb, I head for the pattern. I've never practiced the more subtle decision making that one needs for relatively safe 'low saves'. I avoid struggling for lift below 1300.

If I changed my home airport to a place with a nice winch, a big flat field, and smooth low altitude lift (and not much sink, gusts and wind shear), I'd roll back my training, take a few hundred winch tows over a summer, and fill the low altitude flying gaps in my training. Maybe some place in Germany... The only thing that I've ever practiced below 1300 is circling in smooth easy lift and landing.

I'm an adequate and well-trained pilot for how I fly. If I were a 'natural pilot', I might feel differently. Going to a one-off, auto/winch towing camp would be a good experience, but I'd not have too much confidence in my fresh ground launch endorsement until I did a few hundred launches. People who did their initial training with ground launch have deeply rooted skills that I don't have. I could probably get a ground launch endorsement with a brief effort, but my skills would be thin.
