List would be quite long if this was ten years ago but besides some stupid pressure and late flip stuff that were always very set-up dependent by definition, I've managed to get all of them back and then more. In general, basic logic is, if you've had a trick in you before then there's no reason why you shouldn't be able to replicate it (unless a downright technical one, e.g.. due to an injury, etc.), especially if you're older now and it was your seventeen-year-old self already doing it.
The obvious obstacle is finding enough spare time to physically condition yourself for skating again if you've been slipping for a while, but I think willpower can do wonders there (forget about looking for excuses; overweight due to slobbing it out? Then instead of whining about lacking pop and feeling heavy all day to everyone in the vicinity, ruining their sessions, if skating really is your number one priority, just take it upon yourself to learn to eat better and slim down) and also, maybe most importantly, not locking yourself in that mindset where you're now officially old and can't do anything but step hops and shuvs, sometimes a frontside slash and maybe a nosegrind - as that's just bound to kill your personal perspectives right off the bat. I've said it several times before but if that sounds just like the common approach in your circle of friends then approaching skating differently, maybe by skating solo more or occasionally with younger kids in energy overload mode might help one get out of that 'I'm old' mindset which, from my experience, seems dangerously contagious.
