Fair enough. I will admit that despite my love of recumbents they are probably inferior to uprights at weaving through traffic in city centres and seeing into junctions, making them slightly slower through stationary traffic, even if they're faster through moving traffic. But not yet inferior enough for me to justify getting a upright for the purpose of commuting (at the moment I don't own any uprights).
Some pretty nice bikes 'n trikes you've got there. I do rather like the design of the Quest - simpler, but I'm sure no less effective than the all-singing, all-dancing likes of the Leitra and even Go-one.
