Hi David,
I have seen a couple of full dress Edge X Classics adapted to the Tundra undercarriage with good results. I have also seen one of them get mud on his wing sprayed up from his tyres when landing on a wet grass runway, but it's much easier to hose off a bit of mud spray than having a nose wheel dig in.
The other advantange of course is greater confidence with beach landings, of which I've done a few with the standard Edge X undercarriage, being very careful to stay on damp sand and try to minimise weight on the nose wheel.
If you use a Wizard wing then the bigger tyres are well suited to get you in & out of virtually anywhere, naturally the Streak wings require greater care on short fields or short ocean/river/lake beaches.
Though always remember the rules about minimum separation from the general public (100m) if possible. Other rules on this are a bit grey, landing below high tide mark at low tide I think is ok.
Rgds,
Glen
