I recently purchased a Soul to supplement my Zesty, mainly because I felt a bit overbiked for some stuff and also because..well you cant have enough shiny bike related things really can you?
I have to say riding a hard tail again was a bit of a shock, so much so that I wondered if I'd made a mistake.
1. I just can't go as fast downhill as I could on the Zesty, as line is so much more important and you don't have the ability to plough through things in the same way ('talent compensation' :)). The shorter fork also initially made me feel like I was far more likely to go over the bars on steep drops…
2. You can't just laze around in the saddle over moderately rough ground and rely on the rear shock to soak it up. This means far more out of the saddle work and knackered legs (at least at first)!
I've stuck with it though and now I find I love the lightness and directness of the Soul. It's really versatile and nimble and I think my riding overall has improved.
Still love the Zesty mind. For all-day comfort over gnarlier stuff and for instilling confidence and grin-ability it just cant be beat!
