Hi, I was thinking about ordering some drums and 18' 12' and a 14' of one of these sets...I know the Stage is Birch and the Tour is Maple..I was just wondering if the Tours were heavier. I don't mean the wood type comparisons necessarily as much as the actual drum model types...One wood could be heavier than the other but then there are the ply thickness to consider etc...If anyone has some insight on these drums, I would appreciate it...THanks.....
