I got a 5 piece in midnight blue in 2004 as my first kit. The Philippine mahogany shells are a step up over other beginner drum kits in this price range that use basswood shells. I switched out all the stock heads for Evans and it sounds alright! In my experience, these shells sound best tuned on the low end, as is expected with mahogany. The sizes are 22x18 kick, 14x5.5 snare, 12x9 13x10 toms, 16x16 floor, and are best suited for rock but can be used for other styles.
I think Tama is a wellknown name by his drums quality. Its a really good instrument, and the snare is perfect! I may sell the drum someday, but without the snare, there's a unique sound that I really like. So, I live in Brazil, and here we need pay attention for humidity and the weather, but I never had problem with it. I use Dudu Portes Drumheads (brazilian set), Gibraltar Ironmongery, Orion cymbals and a Mapex double kick.
