depends on the trucks, depends on the curb
for this type of spot, i really liked the setup i have for it. i tried lots of different stuff.
https://streamable.com/72z6kjthe grass is dug out a bit on the other side of the curb. what i am doing here is pinching the back truck on the inner corner, and pinching the front truck on the outer corner. this seems to be the most consistent way for me to stay on the grind as long as possible while maintaining a lot of speed. i think its actually better to pinch it the opposite way, with the back truck on the outer edge, and the front truck on the inner, that makes popping out a lot easier.
when i tried with smaller trucks, this pinch is a lot harder, but still possible. i thought maybe if i just got in really good heel or toe locks i could grind forever, but because its a bit slanted i think you will always fall off eventually. was trying with 139s and 144s.
when i went with bigger trucks (169s) the trucks actually eat the entire width of the curb. i thought that would be really good, but it turns out you lose all your speed really fast bceause so mcuh metal is making contact with the curb. also, to get out, you need snap a really big ollie out, but its hard because you are ollieing just off trucks but since you are straight on its harder to get yourself away from the curb because you dont have that edge pushing you off like you normally do. its very easy to catch a wheel and slam on exit.
