Grinding Advice?

Hey all,
During grinding…how do you remove yourself from the rail when you decide your done grinding… i find just going off the end of the rail is quite hard…

also… when doing crank grinds on ledges… does anyone feel their pedal stop/ slow them down considerably?

I remove myself when grinding by pulling up on the seat like i’m jumping.

I usualy dont try to do grind with my cranks, I try and use the pedals to grind.
But yes, it slows me down or just stops me, that why I try using the pedal only to grind.
I think its because of the wax that skaters put on ledges doesn’t reach as far as the pedals go when you are using your cranks, so the pedal gets caught on the concrete that isn’t covered in wax.
