What a difference! Now have a car I can enjoy - rather than sell! Motorway, A roads, B roads - all so much better. There's a subtlety and compliance to the suspension that didn't begin to exist before. Will 'review' further in a week or so. With many thanks in the meantime.
A run through the North Cotswolds today on demanding B roads. The car is a revelation. Although the low speed ride is much improved, your alterations really get in to their stride as the speed builds; the faster you go the better it gets. The car retains composure at all times, soaking up bumps, undulations and corrugated a. Not a soft ride, which would make the car unsure, but great absorption. The softer rear is so much better than standard - improved traction, and all the jarring and pitching taken away. Because the ride is no longer 'wooden', it has the effect of giving the steering more feel, which in turn allows greater confidence when pressing on. A car transformed! Congratulations to all concerned.
