Pink Mediums are similar to Contact 35 in shore rating, perhaps a little softer.

However, the blend of rubber is different between the Mardave brands and Contacts. The Pinks seem to have good low speed grip (thanks to the soft shore rating) but offer a little progressive release in grip at higher speeds, probably very close to what you are after I think. It is hard to put into text but Contacts seem to give grip, grip, grip, grip and, if you really push them, they are themn prone to peeling off the rims or grip roll. Pinks give grip, grip and then gentle, progressive slide. Like LongRat says, less chance of chunking this way. At least, that I what I have also found on the various tracks I have raced on.

There is nothing specifically wrong with mixing and matching tire brands, pick what works for you.

Hope this helps,
