Kickflips. It feels like my grip is either too grippy or too slick 99% of the time. God I fucking suck at kickflips. Kickflip variations, no problem. Heelflips, no problem.
I also don't do enough of them. I'll get them pretty dialed but lose them quick.
2 things really helped me get them back after losing them for close to 10 years. I could do variations of them (Varial Flip, FS Flip, FS Half Cab Flip, fuck BS Flip variations).
1) Ankle strengthening exercises
2) Adjusting my wheelbase by tweaking my truck setup
The latter really helped since I was getting so much ghost pop and all my kickflips were going rocket. Had to force myself to wait for the pop before flicking my toe.
What kind of kickflips are you getting?
Also fuck heelflips, I hate them with a passion due to my inability to do them.
