i play
tama rockstar and imperialstar kits and love the way they sound especially for the price i mean there are better but
tama are really well made and i love the deep fat kick drum sound they have compared to some other kits...but anyway as far as picking add ons i would go with the 14" cuz i feel it would be more versitile than the 18" especially if you already have a 16" and if you're looking for hardware IMO
tama is some of the best you'd be hard pressed to find better...plus they make one of the best kick pedals Iron cobras... but everyone has there opion!!!
