Did you measure the distance between the dropouts precisely. I would be surprised if it were not 135 since my Challenge Seiran is 135mm.
If you want to save a few pounds at the expense of 70g or so, compared to the Hope, I would suggest a Shimano XT hub or even a Deore. Shimano hubs are pretty indestructible if you regrease the bearings once a year. Speak to Al at Wheelcraft - he'll build you a very good wheel for less than most - 01360 312 709, and pretty quickly too.
