I make mine soft too, I just tend to focus more on making the springs
and shocks soft and then using the bars to eliminate most of the
lateral rolling (one thing I took from the recommendations of the
Jasper engineer, actually). The end result is similar tire wear/temps
but a car that suits my style more. At some tracks I'll have a rear
tire that's too hot (at Watkins Glen for example, the left rear heats
up too quickly with my baseline setup) so I just make moderate
adjustments to either the crossweight or do some weight jacking with
the springs. I'll also often run a bit less spoiler and shift a tiny
bit of weight forward depending on the circuit, since 70 seems less
than optimum at most tracks.
To me the debate over setup/style seems fairly obvious and can be seen
almost anywhere in road course racing. Team Lotus in 78 is a good
example. You have Mario, who preferred a car that allowed him to keep
moving forward in corners with minimum lateral rolling and Ronnie, who
preferred a car that he could throw around with reckless abandon. Not
much of a difference in skill or results at that point in their
careers but 2 completely different approaches to setting up and
driving the same car (and one of the last years in f1 where those
approaches were valid, actually, since ground effect required stiff
everything in order to keep the tunnels close to the ground).
