I've been reading about Vi, she looks like an insta buy for me. Yet i haven't been able to play her.

I was wondering if she seems viable in he jungle at all? As it's one of my favorite roles

I don't see why not. Start with W and max E first. I can see it working.

Yeah she's pretty decent, not the best but her clear times are well if she positions the minions appropriately. Her ganks would be pretty solid as well, almost guranteed kills post 6

in my opinion, yes i tried her out in bots. her passive makes it easy to pick up early buffs and some ganks. her q is great for going through walls (getting to other camps quicker) her w is great for the jungle her e is like MADE for it, it can kill multiple jungle creeps at once. and her ulti is a great gank initiator and or finisher. all-in-all to me her in the jungle seems like she belongs there

Ive jungled with her a couple of times. Took E first (that way I can trigger her passive and eoe clear), W second and Q third. Pretty much the same I go in lane. He jungle clear is quite crazy, her sustain is alright but it is challenging to gank pre 6.

Yeah she is viable but I would start E first so you can increase your clear times. Her E hits initial target and those behind it so positioning can let her clear pretty fast. Her ganks are good too because her Q can initiate or her Ult.

You have to remember that if you start with E while waiting on creeps you will get the two stacks of the skills. So you can use the E twice as soon as it's up.
