I'm one of the rare few who want to keep the original shade of the teak.
Sorry dude, I'd have an opinion but I'm waiting to see the results of your poll before finishing my teak! Just got done sanding it, and I'm 95% sure I'll go with teak oil (but I haven't had years of maintenance to piss me off yet). Call me a traditionalist, but natural is the way that I'm headed.
