You keep upping the ante. For $2,000 you can get a KILLER bike. Unfortunately you keep adding more and more possibilities to what I would recommend.
What's your inseam measurement. IOW, do you have short legs or long legs or average. Overall height isn't the critical factor when sizing bikes. It's important, but leg length is critical.
My recommendations, spend more on a good frame and fork. Good suspension is critical. Since you are a clydesdale and over 200 lbs, I'd recommend a fork with a 20 mm through axle. You'll thank me later.
Forget about lightweight! You are looking for a full squish bike with 4 to 6" of suspension travel front and rear, hydraulic disc brakes and some decent wheels.
Where do you live?
