Righto, well the magic is that if you buy one of my ones for sale here you could probably keep the soul too! And they’re both the shorter travel 4.2″ ones.

Clearance wise at the back you can happily run a 2.3 tyre and still have plenty of mud clearance, and there’s acres of it with 2.0s. The mud does tend to collect on top of the front mech and the bit directly behind there, but never enough to foul the function of the wheel or mech.
Riding wise, they’re very efficient in my opinion – happily done all day rides on both the ones I’m selling (the bonus of the 2007 one I’ve got is that I upgraded the shock to one with lockout) so it’s a hardtail when you want it to be as well. It’s brilliant for attacking singletrack, and tracks, accelerates and is balanced beautifully. Weight wise there’s probably a 3lb difference between a hardtail frame and one of these so you do notice it a bit, but it never feels like you’re riding a heavy bike uphill, but really does come into its own on the downs where it feels like it has way more travel than it does.
My personal preference on them is a longer travel fork, but that’s as I had mine set up as more of a fun bike – if I was doing some racing on it a lighter, shorter travel fork would have been on there, and rebas would have been my choice. I generally run the pikes at 130mm, so there wouldn’t be a huge difference. Also, the complete bike comes specced new with 100mm forks, so you’d be fine in my opinion.
Any specifics, feel free to ask
cheers,
