Need Some Help with a Macro

Hey ya WoW Lazy Macro friends
I have been trying to play a Havoc DH and I am failing big time. I kinda have the rotation down but my DPS is very very low for my ilvl (196).
I have made several attempts to alter exsisting macros buy alas I have failed, miserably. I know just enough about making macros to be dangerous, but its not working.
I am currently running 1,1,3,1,1,2,1 with my 190 legendary. I am Kyrian covenant.
Could one of you awesome Macro Makers advise me or maybe make a macro for this talent build?
Any help would be appreciated.
Thanks much in advance.
