Go with attack speed marks, armor seals and magic resist glyphs, and for quintessences pick whatever you want. Masteries are based on attack speed, attack damage, some armor and magic resist and Speed.

Using Udyr Jungle is a very good choice once you get used to it. Start with hunter's machete and 3-5 potions and tiger stance at Lv 1 for maximum effectiveness in the Jungle. At lv 2 get bear stance to stun the blue/red buff minions, it really lets you get more hits in without dying. at lv's 3-5 get pheonix stance then 2 more points in tiger stance, you dont really need turtle stance till you start ganking so hold off on that. Get your boots first then work towards the first phantom dancer immediately for the best effect with tiger stance. After lv 6 max out tiger stance then bear stance, for everything else put whatever points you want into pheonix or turtle stance. You might think this is a weird set but it works great so try it out.

The Set I made allows you to attack so fast and crit at the same time you destroy anything in your path [as long as your game is going good]. The 2 phantom dancers and infinity edge will let you attack so fast and crit you wont even need attack damage items but of course that is just the start. Once you get the black cleaver and quicksilver sash, you can withstand some magic damage and dive in and kill enemies in seconds by attacking swiftly and critting real often along with the attack damage.

Pros - You attack so fast and crit so often along with the added damage you destroy enemies in seconds.
-You can resist Some magic damage and dive into the fight.
-With the quicksilver sash you can activate it to remove any stuns or slows to get out of a bad situation.

Cons - Certain champions that have so much damage could kill you pretty quick early - mid game.
-Lower health than some champions you may fight.

To sum everything up, you can deal damage so fast you kill enemies in seconds, you can activate your quicksilver sash if your slowed or stunned to get out of a situation and with the magic resist you can dive into some fights and deal damage before they try and kill you.

Yes its a weird set but make sure to always use tiger stance with the attack speed and crit and you will destroy anything in your way. Use bear stance for ganking and stuns and pheonix stance for AoE.
