Specialized saddle size

Bwgan

Went down to the Spesh store today and was pretty much ignored by all the staff, so went to the shop next door who measured my sit bones. I measured in at 130mm, the guy said to add on 20mm which puts me in between the 143 and 155mm Romin, but they didn't have any in stock. Just checking flea bay, and wondered what size to opt for?

If you buy from a Spec store you can at least exchange the saddle if it's the wrong size as sit bone measuring is nothing more than a guide.
