Yup I do agree that technically Gary is the best in the open cat, but that alone is not enough. I watch the 21 and other cat and there are lots of great drummers who are technically gifted but guess who won? the one who mixed his talent with showmanship. Drumming is also an entertainment thing, we drummers know that is a good drumming and which is not. Last Saturday's semis, there are mix audience and I heard someone says "how do they judge these drummers? for me its just the same sound" these are the common people who only judge by what they see and hear that's why Gilbert won the "People's choice" award thing and also went to the finals because he's entertaining to watch and technically gifted also. So for me it's not just pure talent, you need to be creative and be different with others.
Peace!
