Throughly underwhelming. I can't even get excited about the Silva jumbo because I really doubt the authenticity of those relics. Topps don't specifically guarantee they are in anyway attributed to the fighter pictured, and after the whole Panini NFL flawless bungle, I wouldn't be surprised if Topps are just chopping up store bought material.
Given the peanuts some of these will go for in the secondary market, I don't think I can really justify buying a box of Topps UFC anymore. More so with the falling Aus dollar.
