I'm around 100kg and often carry 15 kg of kit or shopping in two panniers. Current wheels of choice are 36h Exal LX17 rims on Deore hubs, Spa will build them to last. I've had everything from Open Pros to Sputniks without issue, what do you have on the Roberts now and why don't you think they're strong enough?
Thanks PH I think the reason I have asked the question is to ensure I have the strongest wheels possible if I should take a route over some rough ground. I suppose I have got the cycling version of " Range Rover " syndrome in that I am looking to fit wheels that realistically I will never need. I think what you write makes sense with regard to riding out of the saddle etc. In fact the last time I rode over some rough ground,actually carefully, I did end up with a couple of broken spokes. At the time I had DT Swiss TK 7.1 rims fitted but when I took the wheel into the shop to get a couple of spokes replaced they told me that the rim needed replacing but replaced it with a Mavic 319 rim as they could match the original.
....I'm unconvinced that for most of us..... rims like Sputniks are needed, most of the extra weight is in the braking surface which makes them long lasting and good value, but stronger?......

Well, yes, but me and countless others have been taking our touring bikes off-road without any real difficulties for years......including the old Dunlop steel 27 by inch and a quarter rims, and there aren't any modern rims as awful as those.
There is a big difference between riding sedately along the average bridlepath and throwing yourself down the black run at a trail centre. Somebody already mentioned riding in a way to protect the bike.

You might be referring to Boost, which widened the flange width on hubs a whole 6 mm. I don't think that did much, especially when 29er wheels have like 24 or 28 spokes. Do you think that more spokes in a wheel are a better approach?....

As is quite common on these forums, your experience of breakages differs from that of my own. Maybe it's your larger sample size, but failing all the time certainly isn't my experience. Or as far as I'm aware does it happen all the time to the 30 - 40 people I frequently ride with.
Be interesting to see your modes of failure, maybe combined with a question as to how many times it's happened to people here.
