If you don't want runeword bows then your only other reasonable options are Windforce, Upgraded Lycander's, Upgraded GSA, Upgraded WWS (my fav), Upgraded Buriza (11/3.5 strafe ain't bad due to "next delay").
Helm: Tal's Mask or Andy's Visage, maybe Delirium (no IAS though)
Ammy: Highlord's or Cat's Eye, Atma's isn't good enough IMO due to lack of useful secondary mods
Belt: Razortail for 100% pierce (65%+ skill) or nos coil to get another 10% IAS to hit a higher breakpoint
Boots: War Travs, the +15-25 damage is godly when multiplied by things like dex, skills, might merc, etc. MF and stats are sweet as well.
Gloves: Laying of Hands > Anything for pvm bowazons. +350% demon damage is awesome for worldstone runs or pit runs or chaos sanc as well.
Armor: Chains of Honor, Duriel's Shell, Twitchthroe, Lionheart (awesome for its price), Duress, ed/ias armor, plain IAS armor
For a +10 base speed bow 9/2 strafe is necessary for a nice killing speed, i think 9/2 for +10 base is 120% IAS
For a 0 base speed bow 8/2 strafe on something like witchwild string (WWS) seems necessary in higher player # hell games, this also requires between 110 and 120% IAS, not sure.
