Me?
Nope, I have
1) carbon road bike (pearson Pave)
2) steel roadbike (Genesis Equilibrium)
3) alu/carbon single speed with drops (Pearson Touche)
4) alu/carbon disc braked flatbar (Whyte Cambridge)
I knew what bike I wanted but I didn't want the off the peg spec on offer, so I bought all the required parts (lots of shopping around) and a friend put it all together for me. I documented everything in an Excel spreadsheet. The cost probably did end up a little more than the off the peg, but I got what I wanted and better components (like wheels) to boot
Otherwise, you can call Pearson,
Condor, other small bespoke type manufacturers and tell them what you want, how much you want to spend and let them spec and build it
In terms of how relaxed a frame is comes down to the geometry, the material, the quality of that material, the components and most importantly you!
