Well I've just done a bit over a thousand miles this weekend down to Normandy and back.
Firstly, the 3D's were absolutely rock steady down the Motorways to the Tunnel and Autoroute towards Rouen. Calais to Abbeville was pretty wet, but all was fine.
We headed south skirting around Rouen to Evraux then round and back up to Caen, mostly on D roads. Really heavy rain around Caen to Bayeux, in the Dark too. But no slips, although speeds were mostly only in the twentys as I just couldn't see anything.
Saturday was better, but we only did local stuff, visiting museum ect. Although we did hit one patch of farmers mud that ran for about a mile, scary stuff, like riding on ice, both front a rear sliding around, but can't blame the tyres. Bloody froggy farmers
Sunday we headed south, D999 to St Hilaire is stunning, great test of the 3D's, easy to get the pegs scrapping. Carried on south towards Laval, then across towards Mayenne and then back north to Bayeux and Arromanches. Last bit a bit wet, but otherwise great roads, again mostly D roads.
Monday we left Arromanches in horrendous rain, which stayed with us all the way to Boulogne. Only slips were caused by the French overbanding, but the 3D's picked back up once off it.
So after a thousand miles I am pretty impressed with them. But I have to say, if I was paying for them, I'd reject the rear with its 130gms of weight to balance it. If I get time,I'm going to pop the rear back off and spin it round and try a couple of other positions to see if I can find its best position. The wheel just looks rediculous with 2 and a bit full strips of lead weights stuck on it
