I got a large 2nd hand Bfe from on here the frame was well maintained.
Forks
It would be nice to have an adjustable fork if you can manage it in time. I ride with a fox 110-130-150, don’t have much use for the 110 setting and still not sure abt the 130, the 150 works well for me esp on jumps/tech stuff. It might be a stretch for climbing when fixed at 150mm. A lot of guys seem to think the Bfe works best around the 130/140mm mark, I assume to each his own. Really depends want you plan to use the bike for, I’m not much of a XC type.
Seatpost
I use a reverb on mine, best thing I invested in.
Weight
My bike is on the heavy side 33lbs, also cos I’ve got V2’s/203mm vented rotors (a tad overkill in most people’s eyes) but it works for me. The downside it’s a bitch to climb as I also went the 1×10 route which is great btw
Personally build it to suit your needs and your style… you’ll love the bike when it descends, jumps and tech stuff.. it’s quite a drag for XC stuff though IMHO
IF XC is your thing you might want to look at the Soul
