When I found a shop which offers black titanium bolts, I started to buy these step by step. So I have some titanium bolts in areas where the weight saving is no reason at all, I just bought them because of the black colour... The will to have black parts is the reason that I do not use titanium spindle bolts for example (I haven't found these in black yet).
I just started getting into flatland stuff about 3 days ago and suck so far, I blame my sh*tty bike and lack of practice.
