[Closed] Roadie/cyclocross wheelset - how many spokes to go for?

I do most of my 'cyclocross' riding on road, but occasionally ferret up bridleways or chuck the thing down rocky or rutted trails (e.g. Peaks)

Been using sets of Mavic Aksiums for the past 4 years now and I've finally given up on them.

They have been 20h/20h front rear, with non-driveside radially spoked rears.

They were always pretty crap and flexy, but occasional encounters with rocks and ruts seem to lead to an inexorable terminal decline.

The rear flexes like a sad thing and now requires re-tensioning every 30 miles or so.

So.... for a replacement set of wheels, I'm thinking I might go crazy and get a 32h rear - built with regular 3 cross lacing?

...but is that overkill?

Perhaps I could get away with 28h rear, or 24h?

Thoughts please... 🙂
