I see that you are in a Wintec. Which Wintec is it that you have? I ask because my Wintec 500 A/P is not the right fit for Nelson at all. When I place it on his back with no pad - it leaves pockets of air between his back and the saddle, because the saddle is not arched enough to conform to the shape of his back.
So - due to those pockets - the saddle bridges. Which is not good at all.
I was told that the Wintec CC arches....and that is why I am asking. Do you have the CC? If so - do you find it archs more than the Wintec 500 does?
I need a saddle with more of a banana shape to it - like Stubbens. Those are immensely arched
Wintec 500 A/P:
I can see a bit of an arch to the CC - but I don't know if it would be enough to accomodate Nelson's back.
