Not sure when mine will be done, not long though. I've got the last couple of bits winging there way to me as we speak; Spoon saddle and some red alloy spoke nipples.
Then I just need to get the wheels built up and we're away.
If I manage to get my act together I'd like to get some F7 forks for mine and go rigid with this build but like you, I can't make me mind up without trying stuff first. I think the E4 frame might be retired when the Clockwork is done, so if the clockwork was rigid that would leave me with no bikes with any boing.
(well until the Proflex is done!
