There's three recent fatal accidents due to failed turnbacks.
In a glider with 30:1 glide ratio, turnbacks from 300' are something that students get to do before being sent solo. There are glider schools that do simulated rope breaks from 200' in low perfpormance gliders.
If you're one of these people who limit bank to 15 degrees, ain't no way.
Once I've turned crosswind, I might think about it, especially if there's a crosswind runway available, but I'd be a lot more inclined to land upwind.
