Congrats - It's always harder to win a freeroll aswell (in my opinion) because the fields nearly always max runners and ocourse you get a lot more fish. I also won a premium freeroll 2 days ago and was more happy about this than some of my other wins.
I just gotta say you talk a good game and seem to know what your going on about so I'm sure this will be the first of many - we may be seeing more of you at the tables
