I’ve tried both control and s works versions of purgatorys. S works were too light in the sidewalls for me, control are much better. Spesh tyres are awesome, purgs are best all round tyre for SW Scotland that I have ever tried.
Northwind will be along in a minute as he is a fellow spesh tyre drum beater!.
Run both S-Works and Control Purgatory and Ground Control. S-Works are lighter due to thinner side wall. I found S-Works were good when run with tubes but now I’ve gone tubeless, the rear tyre tends to fold under in hard corners so have to run more pressure. Control tyre is fine tubeless so will be using Controls from now on.
I ran Spesh Storm Control 2bliss all winter, very impressed, pretty much the same tread as Bonty Mud X, but they seem to roll faster than Mud X for me. Piece of cake to fit tubeless with track pump too.
