Short Ledges Need Some Work

I noticed today at the Promenade across the corner from the O.R.B on the Southwest side of the map that one of the short ledges felt really hard to get into. I'm a big fan of bonk to bonk spots. (A short ledge less than a foot, a gap, then another short ledge to combo into.) In this case I was trying to do a       5-0 bonk, pop over the gap to a back Nosegrind. Half the time I tried to lock in to the 5-0 my back wheels would fall through the granite atop the slab of concrete and act as if the granite wasn't there. Then the other half of the time, I would hear a grind sound effect, but nothing would pop up on the trick registry and I was unable to pop out of the 5-0. It felt like 1 in 100 times I would finally get the 5-0 to register lol. I got my clip though nonetheless, but it took me about an hour. Might want to look into this as there may be other spots where it's happening. Thanks!
