yeah looks exactly like my t-pro(except the colour) and 170 cranks should be fine unless your quite short then you will benifit from 160mm like an original t-pro.
For me you need a simple frame colour with something a little different for the rims and bars etc. Just a simple white or black frame with a colour that stands out from the others. The koxx silver sky is a good example.
iv'e had a Mission Compo and have been on a onza t-comp and the t-comp is by far the better one. Lighter and just more reliable than the mission. They last longer and is worth the money by a long shot.
Just try to trackstand on a slight hill first as that helps and once you can do it for ages just move off the hill and do it there and trust me, it does work.
