The last couple of seasons, I used to run the Muchmore Fleta modified series from 5.0 to 8.5 winds, and I always preferred the x.0 versions over the x.5s. They just felt smoother, but that may have been down to the low timing values (20°) I used to run. When I tried to run the x.5s with such low timing values, they would generate more heat und perform worse than the higher wind x.0s. If I was to run modified again, I would go for the x.0s again, but as I only hit the track occassionally nowadays, 13.5 or so will generate better lap times.
