San marco Regal Vintage Comfort for Longer Rides?
 

hello,
I am upgrading some parts on a 1992 merckx I recently bought and one of the items on the list is a new saddle. I am trying to balance aesthetics and comfort ... the bike calls out for a white saddle like the San March Vintage Regal White ... http://www.sellesanmarco.it/en/Vinta...108/Regal.html but I am wondering about its comfort for 2-4 hour rides. The alternative is a Brooks B17 Imperial ... Thanks for your opinions.
