I think I’d be looking at a Spur frame and moving your existing parts over from the Cotic.
No way would I be looking at a Flaremax for your stated need – that would be like me suggesting a Bird Aether because I ride one. Both would be over 30lbs unless you went amazingly bling / light on the build kit.
As above the Izzo / Oiz would be good options if you can find them.
I think the Trek Top Fuel would also be on the list – it’s less long / slack than the sour but still a good allrounder.
In our group of friends one guy has a Too Fuel which he’s riding for everything and it’s taken a lot of abuse including jumping doubles and tables and steep off piste stuff. One guy bought a Flaremax but decided pretty quickly it was too much bike / too heavy and sold it on again – yet are happy with a SC Tallboy.
