Being an old 'guy' myself I've found that getting up on the converter more helps my lights. I leave anywhere from 1800-2600 depending on the track and how I'm 'hitting the tree'. If you can trust the track will be prepped good start to end radial slicks are the ticket and that's a big if.
We're talking 22-24 psi and no wrinkle or growth. This picture is stiff sidewall bias slicks
