Well, I don't think so. I sold Thanaz 8gz because my legs were about to pop out of them, which was the same problem with 71b. It took 6 long months of heavy wear to get some stretch into those and that didnt really work. 29 in 72l and 8sv are perfect for me becaus eof the stretch associated with the wash. I figure 30 will be perfect for 71b and 8gz, if I ever find another 8gz again. =[
