poll for best p4p ever

I was wondering who everyone thought is the best ever pound for pound fighter in MMA history.

I can only choose 10 people for the shortlist so have gone for some big names on the list. I know that some favourites will be missed off (including some of the current champs).

Please vote on these fighters at their peak and not their last fight!

Fedor
GSP
Randy Couture
Chuck Liddell
Anderson Silva
Penn
Frank Shamrock
Royce Gracie
Cro Cop
Wanderlei Silva

Let me know if I have missed anyone obvious!

Anderson Silva?
Longest winning streak in UFC must count for something.

George St. Pierre?
Matt Hughes?
Rampage?
Severn?

GSP

I've just re-watched Silva v Griffin and I can't say that he isnt the current best. However over the last decade, Fedor has delivered and displayed ability and technique like no other.

Would have to be fedor for me due to how long he stayed at the top in Pride which for me was far better than the UFC, the foot stomps and soccer kicks of Wanderlei Silva to his downed opponents were scary, he was great in his prime as was Royce Gracie, there's no doubt that Anderson Silva is the top P4P MMA fighter out there at the moment.

Head said Fedor while my heart said Crocop. Big fan of both but decided on Fedor due to his long long record
