I'm 6'4, 230 and sz. 13 and I ride a Jones mnt twn 161w. I only want a longer board on powder days...which this year has been limited to 4 days of decent pow. It does great for most of my off-piste/near piste and groomer days, so I can't complain at all. I am looking for a pow board (around 165-167), but with the winter we've had this year I just can't justify it.
Also, for the big feet, I've found Ride to have the best foot reduction. K2 wasn't bad, but for some reason I wasn't impressed with Burton's reductions. Deeluxe also had great reduction on some boots, but they were too soft for me.
