I only seem to post in these type of threads but stuff it, I’ll give you the benefit of my personal experience having made the switch.
Last December I took my Cube Stereo to bits and transplanted all the parts on to a Stanton Switchback complete with a 160mm fork. So far it’s working for me. I’ve done a couple of Enduro races (not as many as I’d have liked due to family commitments) and loved the buzz of being in a minority. I’ve also done a long weekend in Peebles/Innerleithen and had an absolute blast although we didn’t ride the off piste stuff at Inners we did ride some of the DH runs.
Most of my riding (about 80-90%) these days is around Cannock Chase.
To a point raised a few posts back, you can’t simply rationalise that a hrdtail is only suitable to certain terrain/trail types and is more to do with how you ride and what you enjoy. My riding style I guess has always been pretty aggressive so I guess I’m happy muscling a HT around. I love how snappy and responsive it is compared to the Stereo. Yes, on long rides it’s not as comfortable but at the moment I can live with that (that said a typical ride for me is 20-30 miles on & off road).
I do find myself lusting after another FS and over time I might well indulge.
It’s definitely a lifestyle choice that doesn’t suit everyone so I’m not going to preach about how much more bad a$$ riding a hardtail makes you! Just think hard about what floats your boat when you’re riding and whether the bike you have suits that style!
