help progressing!

right so ive been unicycling for about a year. I can ride pretty much for as far as I want but am really limited when it comes to tricks. I practise in the woods which really helps with balance and stuff because theres tree roots and pot holes and stuff so im a fairly confident rider. But I dont know where to go from there.

I can bunny hop small amounts but my uni is kinda crappy so not very good. Would it be worth buying a trials uni do you think?
Can turn confidently, ride backwards a few revolutions but thats bout it.

Any help would be greatly appreciated. videos would help loads as well thanks.

freestyle is always good fun, you could learn to wheel walk and learnd 180 and 360 unispins which dont put much strain on parts.
