There’s a big difference between something like a Bfe and a Trance or Epic.
Forget the Bfe or Blender if you want “snappy”, they’ll weigh roughly the same as your Spicy.
I’d go lightweight if I were you. Just got a Carbon 456 and would recommend that as being very fast and responsive but also very versatile. They’re doing some great frame and fork deals now.
Or in FS the Trance is very lightweight if you get a post-2007 frame. It rides nice too. Watch ebay for complete bikes, lower end ones can go very cheap and you could upgrade over time. Have you thought about an Anthem X also? I’d rather have one of them myself for XC.
