Then I saw a Solaris frame going second hand so decided to give that a go. To be honest I expected to just end up with a slightly heavier, less efficient version of the FF29 and that would be the end of my HT experiment. In fact, it's totally different and I've been amazed at just how capable and fun it is.
Same here. I bought a Solaris last autumn with the aim of preserving my Ibis Mojo from the worst of a Peak District winter. I haven't ridden the mojo since, and I'm not sure when I will again.
Also on the point of HT vs FS, I've always found everything perfectly rideable on either, it's a just a case of the FS being faster and requiring less thought/concentration. Personally my favourite type of riding is picking my way down steep techy terrain and I find a HT much more fun for that. But if going fast in a straight line is your aim then a FS is obviously the better option.
