hi guys. i suddenly want to buy one lol.

googled around a bit, and one fella [ lost the weblinks 'cause i forgot to bookmark it ] sez that there are 4 types, namely A, B, C and D. anyone can explain what those are for? any difference in quality, or the nice sound it makes when you flick it open with any of those that got the A, B, C or D markings?

damn i like the Gudang Garam one as i can only inhale ori Gudang Garam 16's [ and Dji Sam su, both the thick - ended rolled ones and the Dji Sam Su Gold lol ]!
