Glad you got sorted,I think you'll find atleast the rim and spokes will do the job very well,I've no experience of Hope hubs though except for friend of ours who had 40 spoke Hope Big 'Un's on his new tandem,he had nothing but trouble with them.Thats not to say all hope hubs are bad but his were aweful.
Maybe I've been lucky with Hope then, I've had nothing but total reliability so far with 4 ti-glides and various fronts between me and "er indoors" - tho always useful to know of other (different) experiences. Maybe I'll steer clear of the tandem Big'uns. It would be useful to know what the problems were that your mate had - was it anything like cracked shells or bent axles? The first Ti-glide I bought had rather dainty flanges and the drive side split - they immediately sent me a replacement shell with no quibbles and it's been superb ever since - bearings still perfect. All the others similarly excellent, even the ones in constant use over 20 years have only had one or two bearings replaced ever.
This new pro 3 mono is a quite a different design internally - hopefully as reliable... fingers crossed.
