I have been on a rather long saddle quest for some time now. I have been looking for a saddle for long rides with cycling bibs but one that I can also tolerate for commuting (9 miles each way) and short slow rides with my kids.
the best long distance saddle I have is the brooks b17 which has 600 miles and very comfortable in bibs but not comfortable without.

I have demoed many SMP saddles which have been torture apart from my last throw of the dice which is the SMP Plus. I can actually ride this to work with no bibs, I am not uncomfortable but not comfortable either if that makes sense?! I guess it will be even more comfortable with bibs?

I get no numbness no sit bone pain but as you sit on or in these saddles differently I am getting irritation on my bum cheeks which I think is because the tail of the saddle anchors the back of your bum which is not what any of other saddle I have used before does.

so what I want to know is, is this sensation on my bum cheeks normal for SMP saddles and will they toughen up as I get used to it more? Or am I sitting on it wrong? I have a fairly upright position on my Marin muirwoods using an on-one OG bars. I am not sure if the SMP professional range are made for this type of riding but guessed the SMP plus is wider so could be used for this type.

I am fairly slim build too with 110-115mm sit bone width 74kg.

any advice would be great!!
