My vote is if you want it, get it. I don't think you are to big for that frame, at least the 19 or 21 inch versions. the m5 is super stiff and would transmit the power of a big man well.
But, keep in mind what LC said. It is a race frame, plain and simple. Harsh and stiff. Use it for what you will, but don't expect to feel comfy or compliant. I would expect a harsh commute.
the same applies to the epic. The s works epic frame is a race day frame. Super light and carbon a plenty. It will be less harsh but still not the best choice for general riding.
I must ask, why do you want such frames. Do you plan on racing them?
