Hitman – its too personal – ime. Some folk here recommend Charge Spoon. If I ever meet them I'm going to kill them. Slowly and painfully. Just cause their recommendation did it to me! And it was heavy – around 50% more than the pack said.
Any way – your ass is different. Mine hates hammock shape saddles. Some hate wide. Some hate narrow. Some hate cutouts. Some need cutouts. Yours needs something ???.
I'd say start with what you have and see if it's hammocky, wide, cutouts… Then buy the opposite – or at least different. Otherwise go to a Specialized dealer and they can help a lot – ime.
BTW- here's my saddles-
Charge Spoon
WTB Rocket
Selle Flite
SDG Belle Air
Selle SLR XC Gel (favourite)
Spec Phenom Gel (2nd fav)
Gobi
….
Oh – Apart from Selle (with their chicken money back g'tee) I buy them all 'used once' on ebay. Saves a fortune.
