heres what i did, i was looking for the same thing, with looks in mind too so i really wanted 17s, but looked at alot! of 16s because they were around 11-20lbs depending on brand so i finally set my mine on 17 racing hart evo s7's that are awesome looking yet really light for a good looking 17 , and i still dont think i could have found a better wheel, so i would just do my research and dont! get in any hurry to buy some, i looked for about 3 months to get my heart set on mine. and i love them
Racing Hart Evo S7s are nice, I would consider buying a set if they were 16s. Konig Heliums are also lightweight, but they dont come in 16 I dont think. I like those Rota Circuit 8's also, they are Mugen knockoffs i believe, but I dunno about weight. Rota slipstreams are cool too, and lightweight. They are Knockoffs of the wheels I will be getting, Spoon SW388
. In the end, its up to you, and like Kevin B said, dont rush, cause you will end up getting something you regret.
Edit-I think 16x7 wheel is perfect, just my opinion...
