The aero penalty of SS + arm warmers vs LS must be pretty tiny.
I was only expecting to properly TT twice this year. So figure SS was the more useful option even if I use arm warmers 90% of the time. I also have short arms so at least SS removes a fit question mark.
I was thinking 0,5 - 1,5 w at TT speed (40kph). Probably less if you consider the arms of a LS will need to be folded somewhere. Guesstimates obvs. I'f I cared more I'd have invested in more 'tested' skinsuit i guess.
