Heres a few I made a long time ago, they are still the 1's i use today tho:
Ok...most of the time for cowing zons Java Zons would be your best bet...but with the right gear a bowazon can kill faster then a Javazon...I will list a build for both of them and u can decide which 1 you like better....list your comments and changes below.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Bowa-Zon
This kind of zon is my preffered type..due to the fact you don't need much mana or mana leach, and its more fun shootin cows then throwing sticks at them .
STATS(base):
Base Mana(with mana leech this will not be a problems period)
135 Strength(This is enough strength to use every bow in the game....as of 0.9)
100 Vitality(you need enough health that u can stand a hit or two..incase a moster gets by your shots)
rest of points in DEX(DEX gives zons pure damage, like STR gives barbs damage. DEX also gives Attack Rating[AR] without Attack Rating you will be lucky to hit one cow.)
SKILLS:
Max Guided(you dont want to have to watse all the time shooting multis at a single cow)
Max Multi Arrow(The best cow killing Bowazon skill there is in my opinion)
Max Critical Strike(This gives chance to do double your regular damage..so instead of 1000-2000 you might do 2000-4000)
Lvl One Peirce(this is not required with a razortail because of the peirce mod)
Max Dodge(so the cows have next to no chance of hitting you, which wil save you if you are lagging etc.)
Max Penetrate(Adds % to AR...very much needed for cows)
EQUIPMENT:
FOR THE NOT SO RICH
Weapon: Buriza or Goldstrike Arch
Armor: 60 Increased attack speed armor(4 socket armor with 4 15% IAS jewels)
Helm: Vampgaze
Belt: Razortail
Rings: 2 Perfect Ravens
Boots: Waterwalks
Gloves: and gloves with IAS and Knockback(KB)
Amulet: Cats Eye Amulet or Highlords Wrath...Cats Eye will help more (you already have critical strike which is pretty much the same as deadly)
FOR THE RICH:
Weapon: Ith Crusader/Hydra bow with 440 Enhnaced Damage and 110 IAS..or Winforce with 40/15 IAS or Cham rune
Armor: 160 Enhanced Damage 60 Increased attack speed armor(best bet would be archon or dusk shroud)
Helm: 120 Enhanced Damage 45 IAS Bone Visage
Belt: Razortail
Rings: 1 Perfect Raven and 1 Corruption grip/Viper Whorl
Boots: Waterwalks...or Horadric Hacked boots wuld be good
Gloves: 20% Ias Knockback gloves..with Life or mana leech if you want
Amulet: Cats Eye Ammy...CliffKiller ammy if you can afford
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Java-Zon
Many peoples preferred zon..due to its possible enourmous attack power and quick cow killing.
Skills:
Max Lightning Fury (Easily the best cow killing skill out there)
Max Critical Strike (This gives chance to do double your regular damage..so instead of 1000-2000 you might do 2000-4000)
Max Dodge (So the cows have next to no chance of hitting you, which wil save you if you are lagging etc.)
Max Penetrate (Adds % to AR...very much needed for cows)
Max Peirce(very much needed in all parts of the game)
Rest Of Points In Valkerie(good distraction for when u pwn those cows)
Stats:
Base Mana(with mana leech this will not be a problems period)
156 Strength(Enough Strength For StormShield)
100 Vitality(you need enough health that u can stand a hit or two..incase a moster gets by your shots)
rest of points in DEX(DEX gives zons pure damage, like STR gives barbs damage. DEX also gives Attack Rating[AR] without Attack Rating you will be lucky to hit one cow.)
