@ XATM,

Why not just use a 1 button tanking macro too... then you don't even need to click-cast. Something like this should work:
/Castsequence reset=combat Judgement of Light, Hammer of the Righteous, Consecration, Shield of Righteousness, Holy Shield, Hammer of the Righteous, Judgement of Light, Shield of Righteousness, Consecration, Hammer of the Righteous, Holy Shield, Shield of righteousness
This should give you a good start on your 9696 tanking rotation, and because it is run twice, it will automatically reset (i.e. if you manually run the 9696 rotation twice, it starts over). Tanking rotation solved... lol

You can use this addon if your macros are too long for the standard interface:

Found that ^ addon in another thread on this site (can't remember which thread).
