i found that rush static after machete was best for jungle. just gank ALOT.

Hydra has better clear times in the jungle and you get a higher burst when mixed with your ult as compared to botrk. The botrk does better against tanks and bruisers but your job as yasuo in TT is to kill the squishy before he can kill anyone. As for the merc treads EdisonKhoo gives the reason for them the only time I don't take them is if i plan on getting a zephyr.

^ Actually Mercury's Treads is a situational item. If the enemy doesn't have any CC, you better don't buy it. But most people in TT will choose champions with high burst and high CC, so it is good to buy it.

I'm basically buy a BOTRK instead of the Hydra and I didn't get why you bought a Mrecury's Treads instead og the Berserker Graves. However, + , good guide!

I will start by saying that my experience with TT jangle Y***y is very limited. However, i found that I really liked Grez's Spectral Lantern much better as a jungle item. It's cheaper than the Spirit Stone line and allows you to speedily jump into building your Shiv. The only downfall is the loss of Machete. Just something to ponder. Also, I feel that Wind Wall is better as a "one and done}} spell that just needs slightly more practice to place both quickly and accurately. Maxing Sweeping Blade second gives you more burst mid game (which is when you start to really shine) and more mobility (slightly less cooldown between jumps and less time to wait to jump the same target). Overall pretty good guide though. Needs a wee bit more to it but what you have is nice :)

The guide is meant for Twisted Treeline which does not have Infinity Edge and is replaced with Lord Van Damm's Pillager

I am not really sure why haven't you bought Infinity Edge, but neverless its still a great guide.
