i think if you were able to do a (lower) trick several times it will be very easy to relearn, at least at a rather low skill level.
What concerns me i have never really "started" freestyle in the way that i was training mulitple hours per week, and i also never quit, but when i occasionally freestyle i can relearn tricks quite well.
But there is probably a difference when it comes to harder tricks, where you have to get your muscles used to the quick movement again, or also for long combos, where you need consistent good touches and stamina as well, what you can't just relearn like that.
I guess that's why you find it easier to do 3 latws than long combos.
