I have the Dutch EZ system and am very satisfied. Of course I have not tried any alternative, but I am very happy with this one. EZ delivers both manual and speed sensitive regulation. Mine is was fitted as manual, without anybody really asking which I preferred. Perfectly ok with me, I prefer to be in charge myself. Hence my recommendation is manual. I seldom change the setting, though. It is on full power almost all of the time. Recently I have fitted Michelin Pilot Sport tyres, which are very sensitive. On the verge of being nervous in higher speeds, so I might experiment with reducing the power. The EZ has been fitted to quite a number of Morgans here i Norway, everybody is happy as far as I know.
