The best to buy are probably treeform V-spreaders. I like simple and easy myself… I havent used them but as far as i can tell they last forever and just do what they are supposed to.
The lathing interests me… not saying its the best but same concept. And more user friendly for stone fruits.
Stretchy bands are also very interesting to me… i think i can pull something easy off with some bungee cords i have laying around.
I got these ideas here… sort of pedantic but i learn that way.
