There's nothing wrong with the qualifiers, they're just a bit newer so not as many people have tried them. The deal with DLIT's tires was that they were OEM, and hence much harder than standard qualifiers, and even had a different tread pattern. My qualifiers have about 3k miles and 2 track days on them, they've worn fine, but I don't ride in many straight lines. Unless you're on the track really pushing yourself, the only difference between the Pilot Powers, Qualifiers, and the BT012SS is the profile, all of the compounds are very similar.
That said, the Pilot Race's get put on tomorrow. I think I'll try some BT002's after I wear out these pilots.
