I managed to break my straps as well...
2000 jumps were probably too much for them

With a wider stance you have more leverage and more options to distribute the weight on the board. So I feel like it gives me better overall control, I can throw around the board easier and also load it up better.
When I'm powered and jump around I also like to ride in fully ducked, it allows me to hold more power and then be more explosive when taking off. So nothing wrong with that imo, it's not your fault when the straps can't take it.

As said, knee problems are the trade-off with a too wide stance, so be aware of it.
