Barons are brilliant but designed as a damp tyre (they were originally sold as Rain Kings). Not as grippy as a Minion or equivalent unless things are muddy (though, they’re never bad). I took Clutch SXs out to Les Arcs last year and they were bloomin brilliant, will be using Butcher SXs this year- grippy, and very tough, but not as hefty as a full dualply, better than a Minion and cheaper.
Where are you actually going? If it’s a trailbike-style holiday then don’t get too carried away.RP23s are great, and reliable- people literally pointed and laughed at mine when I turned up on my Hemlock for the fort bill endurance dh but it didn’t miss a beat, quite a few coil shocks popped though 🙂
