I have a Zesty 514 and I find it amazingly light and fast for climbing and it loves smooth flowy singletrack.
I am, however, going to change the stock Fox Float RLC 140 fork to a RS Revelation 150 as I find the Fox too ‘lively’ for the kind of rocky stuff I like and have always ridden RS finding them plusher and more controlled. I think the year after mine 2011, had RS Revs as stock.
I personally think the Spicey is overkill for most UK riding (even in Scotland, where I’m based) and the X Flow is much more of an XC bike.
Horses for courses!
Test ride if you can, though I didn’t and still love it.
