Every shop I've worked in mostly used Pedros. The Park are also fine but not my favorite. Maybe there are better? Levers tend to walk so the low price of the Pedros is part of their ubiquity. Sometimes an honest to goodness metal DH lever is what you need but is a dangerous tool in the wrong hands and usually a bad idea (that TL5 you're not sure about? It's for real, wire bead, double casing DH tires with a particularly tight fit). None of my bikes have particularly challenging tire fits so I feel pretty whatever about the subject. Good technique is the main thing that makes flat fixes fast--and a good compressor with a pressure gauge head doesn't hurt.
