5 Rogues and talent advice needed

Tasty you are a nut.

I found a some abilities would get hung up so I changed my melee button. Here are my current macros:

/dismount
/stopmacro [nomod]
/assist [mod:SHIFT,nomod:alt,nomod:ctrl,target=Rowg][mod:CTRL,nomod:alt,nomod:shift,target=RÒwg][mod:SHIFT,mod:CTRL,nomod:alt,target=RÓwg][mod:ALT,nomod:ctrl,nomod:shift,target=RÕwg][mod:SHIFT,mod:ALT,nomod:ctrl,target=RÖwg]
/console Sound_EnableSFX 0 
/script UIErrorsFrame:Hide()
/use 13
/use 14
/castsequence  reset=10/target/combat Shiv, Kick, Sinister Strike, Sinister Strike, Gouge, Expose Armor, Sinister Strike, Sinister Strike, Sinister Strike, Shiv, Slice and Dice
/script UIErrorsFrame:Clear(); UIErrorsFrame:Show()
/console Sound_EnableSFX 1

This is my stealth button for my main. I was thinking about adding a castsequence for sap (would have to create new keyclone hotstrings, though.

/cast [nostealth] stealth
/castsequence [stealth] Sap, Pick Pocket
