Seat angle, shifters, groupset: Viper sports trike

  1. Thinking about a Steintrikes Viper, it's an affordable sports trike. http://www.steintrikes.com/ and
    http://www.yunord.net/~bikeplus/trikes/trikes.html

    The purpose is to get something fast for track racing, training on the road or better cycle tracks,
    and audax events. As I'll have it for a while I'd use it for some touring and commuting (not in
    traffic) as well. I can use my upright hybrid as commuting double.

    This led me thinking whether 25 degree seat angle is comfortable in most situations... or should I
    go for example 30 degrees. The compromise could be useful for touring and commuting of course, but
    how about audax stuff? Does anybody here experience discomfort because of neck straining/craning on
    a say, 100-600 km ride, when riding with a seat angle around 25 degrees? Higher seat angle would
    compromise some speed in the sprints, time trials and road rides... Then again I could perhaps get
    some speed boost from a fairing, but even faired vehicles are faster with a low seat angle I gather.

    I was thinking of getting Dura-Ace bar end shifters, would they be the best choice? For gearing I
    could use triple crankset with large jumps between the gears, for a good range, and in the rear
    alternate between eg. 11-34 megarange and 11-23 road cassette. 9 speeds on the rear. I think it's
    a rather mixed groupset (Deore, Tiagra/Sora, and what have you...), any compatibility issues I
    might miss?

    I started thinking about a racing trike and now it's all the time going more and more towards an
    all-around vehicle... deja vu! Looks like it's gonna be so compromised I just have to buy that low
    low racer in a couple of years ;p But that's ok, I'm just starting out with bents and racing...
