This is the final build i reach for my 6 trained champs i wanna store those builds for me but what the hell ! if it can be usefull for others ^^ i can share :) All items are the core/starting main items but after those you can/should go on situational items :) or standard items liek rabbadon for akali etc :)

Mid champ : akali / brand
Top : Shen / Singed
Jungle : Udyr / Lee sin

(i don't like to play bot :p)

For the two jungle champs :

Jungle :

Udyr : Wolves > Wraith (Smite) > Golems > back (Sword) > BLue Golem (Smite) > Wolves > Wraith > Golems > Red Lizard (Smite) GANK

Spell after lvl 5 depend on what you have to do : more gank prefer tiger , tank more and not die while ganking prefer turtle , no gank to do more farm prefer phoenix

Lee Sin :
Early gank : Wolves > Wraith (Smite) > Golems > Red Lizard (Late Smite) GANK
Normal way : Wolves > Wraith (Smite) > Golems > BLue Golem (Smite) > Wolves > Wraith > Golems > Red Lizard (Smite) GANK

Same as udyr after lvl 5 : Sonic for more damage and more gank , safeguard for be more tanky or more farm , and tempest if you can't manage to control ennemies when gank
