Shyvana jungle

I've been experimenting a lot with Shyvana jungle this preseason, and I was wondering if anyone had any input on the build I'm favoring. 0/21/9, 1 red crit, 8 red aspd, 9 yellow armor, 8 blue armor 1 blue aspd, 3 LS quints. Start golems smiting the large, kill red then wolves, kill/smite krog, blue, chickens and back.

Sustain's pretty decent, and I run exhaust/smite so if before or after the chickens if a lane is almost at tower I can gank. There's also a good opportunity to level 2 gank after doing golems/red buff on purple side with exhaust.

I'm doing devourer/skirmisher, botrk/hydra (depending on if we need waveclear or not), zerks/treads/tabi, 3 tank items (I'm favoring Omen/BV) then Solari if we need it, if not scimitar or maw, or thornmail if we need it. Then trading out boots for zephyr.

With the tank masteries there's a butt ton of tenacity/slow reduction, exhaust/botrk/omen for 3x active slows, dueling is insane because of exhaust/skirmishers, and the iron elixir for even more slow resistance/tenacity or ruin if I need to splitpush.

If you catch the entire team in a jungle lane especially with the tiamat if you can land your entire combo on them 1v5 penta chances are huge.
