So, I've decided to upgrade my bass drum heads. I have a Standard 22" bass drum (Tama Rockstar). I know it's not a pro kit, but I want to get the best I can out of it. I want to get a warm sound, and getting that deep "heartbeat" kick (a lot of low end, medium to little attack). I was researching, when I found out that it bassicaly comes down to either the EMAD 2 or the Aquarian SKII (some might include the PowerStroke 3). I don't have access to a local store to test them out on a drum kit before buying them, so I would be purchasing them online. Any advice on which of these should I buy so I can get the sound I want?
