At what point in my skill progression should I buy a park board?
I currently have a NS SL and have no complaints. Even though I kinda wish Id bought a Proto, the SL seems fine for me even in the park. Currently I am only doing 50/50s and BS boardslides on boxes (and ride-on flat rails), big straight airs with grabs on small-medium kickers, and tail butters. The SL handles this kiddie stuff just fine, but at what point in my progression should I consider a more park based board? I imagine at some point having a park board will allow me to progress a bit faster and safer, no?
