Maybe if I tell you what I DIDN'T do, that could help you out. I have no one to talk to about this, so it's going to be a long one.
I spent the whole spring and summer this year trying to relearn them on a curb and I failed. I learned them 15 years ago and got lazy and lost them like a fool.
When I could do them back then, I could only do them to fakie. I guess that was more natural to me. This spring I wanted not only to relearn them but to go out to regular because that's more "acceptable."
But I don't know, that might've fucked me over. I think I was spending too much effort trying to contort my shoulders into a position where I could come out regular. I'm pretty sure that was stopping me from leaning into the slide and pushing it with my toes. I should've just focused on relearning them fakie and then went from there.
I eventually started trying them to fakie but it felt too late; I was barely sliding any, and if I did slide, it would only be for a millisecond.
I'm goofy-footed, and the recurring problem I have is that when I ollie and turn backside, I'll always stick on the curb. My back wheel facing the curb would always hit the curb and I'd land at an angle.
I remember that when I initially learned them many years ago, sometimes I would lock in, slide, and shoot out, or I would land with my back wheels on the ledge (the Janoski). Neither happened this year - I would ollie and if even I got my tail on the curb, I would stick every single time.
The weird thing is I tried relearning back tails five years ago and I DID shoot out of a few attempts, as a result of correctly locking into the curb...but now I can't even do that.
Full disclosure, I think part of my problem is that I couldn't even do b/s 5050s because I lost those as well. But I relearned them, did a few on a curb, but they're also strangely difficult to do now. So maybe it's going to help, because 15 years ago I learned bs 5050s before I learned back tails.
I was trying to take everyone's tips - swing my hips more, keep my shoulders parallel with the curb, roll up at a slight angle, pop THEN turn, try and push with my toes, look at my back foot, lean in the opposite direction of where I'm going...nothing was working.
I know the problem's in popping and turning properly. 50% of the time, when I'd try to ollie on, the board would flop off my feet or hit the curb. My ollie isn't as precise as it needs to be, I guess. For some reason it's hard to correctly visualize landing the trick.
Also the thing that sucks is that it's started to snow where I live, so I'm going to have to wait for five months before it's consistently warm enough to try to relearn them again. There's only one indoor park and it doesn't have anything small enough for me to learn on, if I can even get in due to virus regulations. It's fucked.
Here's an attempt of mine if anyone's interested.
