Poker Variants:Specialize or Learn Them All?

[LouisCyphre]

I started out playing $1/$2 LHE and I am working my way up the limit ladder and I believe SH-LHE is my best game at the moment.
But I also play NLHE,SH-NLHE,7CS,7CS8,PLO,SNGs,MTT. Now I am convined that all of those games are complex enought to not be able to excel at all of them.
Is it better to strive to master one poker variant or should you be versed in more than one?

PRO Specialization:
-------------------
-Faster learn rate resulting in greater hourly rate
-boredom might cause you to play robotic mindless poker

CON Specialization:
-------------------
-Better game selection
(eg.I clear bonuses with 7CS+PLO on sites where HE is a rock garden.Also important in B&M)
-another game might provide a change of pace and keep your mind sharp
-ability to take advantage of profitable opportunities
(eg.MTTs with overlay)
