Saddles?

I have for many years,quite happily, sat on whatever saddle came with my bike. And never even thought about them, as it seems my backside isn't choosy where it sits for hours.

My earliest 'proper' bike was the Viscount Indy 500 and I did 1000's of miles on the suede saddle that came with it. Apart from issues of soaking up rain water, it was fine.

Then I started to get a bit restless. I had never had a bike with a Brooks saddle on it and held off buying one (I am a bit tight with money). But I kept reading about how most people swear by them. I also thought the Brooks looked good on the Viscount's on last summer's Rally.

I decided to treat myself late last year when a used Brooks Colt came up for sale. It was used a little but not broken in.
I picked it because I thought it would suit the Deore 18ax. And it does...

However, I've not done a ride of more than 15 miles on it since then that hasn't left the inside of my thighs sore. My bum doesn't hurt though.

I'm not sure whether to stick with it , accept this isn't the model for me or to go back to the Vitesse style suede that it came with? Any thoughts?

I have been looking around and like the look of this particular saddle. Does anyone have experience of this kind of material?
It seems like a cheaper version of the Cambium?
