I’m sort of in the same situation – but not quite.
I mostly ride MTB and have bikes to cover most options (hardtail, full suss, SS). I also enjoy a bit of road and have a Cannondale Synapse that I really like (so not quite the same situation as you there).
I like the idea of a bike I can use for some winter road riding, but also something I can use for a bit of gravel/lanes/towpath type shortcuts or just mixed in with road rides for variety.
So similar to you but different. You’re not likely to find someone with exactly the same set of circumstances, preferences and priorities though…..
For what it’s worth, I’m very tempted by the Arkose 5 that is currently on sale for £1200. For the price it looks like a great option – even if the colour is a bit iffy).
