Rapha, nice but a bit pricey?

I am 6ft, 65kg 29" waist and have a pair of large Assos bib shorts which fit and a medium pair which also fit (both S5 Uno)
The medium is a bit more snug, but both the straps and fabric have a good amount of stretch (much more so than other bibs I have)

Tights may have a bit less stretch if the fabric is thicker though...

You appear to have the same bodybuilder physique as myself (I'm around 63kg). Think I'll try the mediums, would prefer snug and toasty over a bit baggy... thanks for the tip off.
