I agree, unispins (180s anyway) are easier than crankflips (IMO).
I’ve never had the balls (or shinguards ) to try a crankflip though.
for unispins, you just have to -do it-. As long as your feet land on any part of the cranks/pedals, you should be fine. I landed my first one after about 4 tries, a short break, and then another few tries. i find it easier to land them if I’m trying to “show-off my 1337 unicycling skillz” to someone.
wheelwalking took me a while to learn. I held on to a mailbox and balanced with one foot on the crown, and the other on the tire. then pushed the wheel with one foot, and moved it onto the crown; pushed with the other foot, then moved it back to the crown - repeat.
1ft ww came not long afterwards. i’m still working on gliding, though I can coast a couple of feet while 1ftww’ing.
grinding isnt very difficult unless, maybe, you’re grinding down a handrail along a set of stairs, but so far I’ve kept my grinds to funboxes at skateparks.
1ft riding. well. not so hard. takes some practice, but it isnt as hard as other tricks - though I can’t 1ft ride with my left foot yet.
pirouettes. easiest IMO if you ride towards a person/pole, touch them with one hand, and sort-of pull towards yourself. I’ve done a 720 before. I admit, it’s not as much of a pirouette as it is spinning in place. i can’t do an actual pirouette, i guess
another thing that I like to do sometimes is riding in one direction, stopping, and, instead of hopping180 to change direction, I just throw my weight and spin on the tire. eh, maybe not so cool, but neither am I
I can ride a unicycle though!
