I find it interesting that this debate even occurs. I worked for many years in the 'experimental engineering' division of a major motor vehicle manufacturer. Now it appears to me that Lyco and Conti would have similar divisions. It also appears to me that some of you are saying that we did not have any idea what we were doing, (despite being employed in this are for many years) and a lot of you know more than the people that actually design and build the equipment. Jabba, I wonder how many people know more about your business than you do. On your standard, a fair few I would guess. (first time I have commented on this debate).
