Your job must pay handsomely! Always with the super-pimp updates! I'm pretty jealous of your position - but out of interest, why do you keep changing so much? Almost everyone I speak to seems to prefer riding a bike they know, since they can ride it better.
Do you just like always having the bike surprise you every now and then, or is it for weight-weenying, or just because you can?
All your bikes are lovely, whichever reason it is.
