Run Speed Boosts

[Djeserit]

Which of the following stack and which do not?

Striding item
Barbarian speed feat
Monk movement bonus
Rogue: Thief/Acrobat II 10% enhancement
Thief/Acrobat: Showtime
Expeditious Retreat
Haste
Barbarian/Ranger: Speed boost

Am I forgetting any?

Striding item, expeditious retreat, acrobat show-time is the same bonus, thus don't stack. Probably the barb/ranger boosts wouldn't stack either, but they share cooldowns so you can't use them anyway.

Haste dosen't stack with striding either, but is a bigger boost so good to have.

monk, acrobat 2, barb stacks nicely, tough you can't take monk and barb so that's not sure but a moot point anyway.
