Hi Christophe,
This may be a side topic but the issue you are addressing is "Satisfaction with New Wire Wheels" and that means not only how they look on the car but how they feel when driving your Healey. In many respects the choice of how your new wheels appear on the car is a matter of taste and that can only be your selection. However, there are a number of factors that will affect your satisfaction when it comes to driving and that involves the features of the wheels as well as how they roll on the car.
About 20 years ago I purchased Dayton 72 spoke chrome wires and have been very satisfied...although not always. After my initial enthusiasm and expectation that my "scuttle shake" would be totally eliminated (attributing it to my original wires), reality set in. Although the shake had been reduced significantly, it was still present and ever changing from almost non-existent to significant. As further forum discussions have identified, although all scuttle shake can not be attributed to one issue, many of us have found that imbalanced brake drums are a major factor and the changing dynamic was due to the ever-changing position of the rear drums due to the differential. If you have not yet had your rear drums balanced, I strongly urge you to do so whatever you ultimate wheel choice.
Because of my past satisfaction with Dayton, I would probably still consider Dayton's 72 spoke wires as my top selection but I would also add that such new features as Tubeless and Perma-true would contribute to that decision as well. Again, although the choice of spoke number is a matter of perception and taste, I would also suggest you contact Hendrix or another to make sure your drums are balanced and not inflicting dissatisfaction into your choice.
All the best,
