I've seen quite a few 810s come back broken and sent off for warranty. Yeah, they're light but they can't take any kind of impact at all. The wings seem to get all loose and sloppy over time too. They're great bindings when they're new or for those who are just skiing recreationally, but for park skiing, I find that there are better choices.
DIN setting would be around 4 or 5 I'm guessing. So between a Solly 810 (range of 3-10) and a Rossi Axial2 (3.5-12), the Solly would be more ideal, but considering that progression is a goal, I would consider an Axial2. Or even better, if a Look P10 could be found, that would probably be a great binding to use.
