I'm not the best at front crooks, but I can get em pretty proper if I put the time in (quite a long time these days tbh). But I might be able to help since front nose is one of my go to ledge tricks so we probably have a similar approach to the front crooks.
Instead of 'stabbing' the nose in with your front foot, try using your back foot to get the board to the right angle, like you're doing a backside shifty - you could also think of the motion as being more like doing a back lip than a front board, so getting 'above' the obstacle rather than going 'at' it. Doing the 'stabbing' motion tends to cut the ollie a little short, and in my experience the more you do with the front foot the more you stick. Another way to look at this is to pop like you would for a front nose (to regs, not fakie) but lifting your back foot up more, which will naturally lift your front foot higher. This also lends itself to a steezier pinched front crook with a little yank out rather than falling off the end of the ledge. Even though I'm super inconsistent with front crooks, they're usually good when I finally get em, which I think is because I treat it more like a front nose than frontside nosegrind - this is purely because front nose is one of the easiest ledge tricks for me, and I've probably landed less than 5 nosegrinds in my life. Happy accident though.
After you suss out popping in, the next thorn in your side will probably be sticking. Thing that helped me the most with this was dangling the toes of my front foot over the edge of my board a bit like a heelflip. Feels weird popping like that, but you end up with your front foot on an angle that kind of pushes it along, and it keeps your heel out of the way which is guaranteed stick. Also makes the grind feel more like a front nose.
Getting out is pretty tricky. Main thing is having your feet flat to make sure the board doesn't flip, and not trying to yank it out like a front nose. Gotta be a bit dainty and do a lil crack pop out. Remember: there is no hurry to get back on the ground, so don't yank or stamp. Gotta treat it like a lover. Gentle yet firm. Sensual yet bolts.
