Best MTB disc hubs for cyclocross?

Guys, what are the best MTB disc hubs for cyclocross use (not singletrack). I want to run Avid BB7 ROAD brakes with 6 bolt 160mm rotors (also is it possible to use the centerlock Shimano hubs - or are 6 bolt versions required)?

I am a fairly heavy guy 220# and don't want to be rebuilding the hubs regularly. I would there to be cheap replacement freehub body parts available though.

I am coming from road, and have no experience with the MTB lines. The pre-built disc wheels come with a dizzying number of hub specs! Of these what are people finding are the best option:

Shimano XT FH-M756 (older standard w/ 18 clicks)
Shimano XT FH-M770 - 36 clicks
Shimano XT FH-M775 - 36 clicks
Shimano SLX FH-M665 - 32 clicks
Shimano SLX FH-M667 - 32 clicks
Shimano SLX FH-M629 - 32 clicks
Shimano FH-M529 - 16 clicks
Shimano FH-M590 - 16 clicks
Shimano FH-M595 - 16 clicks

(I could care less about # of POE clicks since these are for cyclocross use only).

I am leaning towards trying to find wheels that use the Shimano XT FH-M756, since they seem to have a reputation for reliability where the newer FH-M770/5 seem to have issues (especially for heavier riders).

Pretty much, IMHO, pick serviceable , but nothing you will cry over if you crash ,
and ruin the rim, but can afford to bring a spare wheel set,

Vs one that you will cry at the thought of replacing them, after the crash,
and you have to retreat to the Beer tent, to console yourself..

There are several adapters that use 6 bolt discs on center-lock hubs.

If you've narrowed it down to Shimano, the higher numbers are basically better (but only marginally better) and cost more.

You can get an adapter to use 6-bolt rotors with center lock hubs, but you can also use center lock rotors (sold separately) with the BB7 calipers.

Shimano makes a hell of a hub. Weight is really the only potential concern in my opinion, but at your size robustness would be good.

If you have more to spend, DT Swiss 240 or White Industries.

Shimano says that the new 29er specific hub: M529 6-bolt and M629 Centerlock disc rear hubs were designed to accomodate extra torque exerted by the new 12-36t 29'er cassette.

This is compared to the (seemingly inferior) M525 6-bolt disc rear hubs https://www.mtbr.com/cat/tires-and-wh...02_127crx.aspx


Does anyone have any hands on experience with the new 29er specific hubs?
