Bipe, I hear ya - a properly broken-in and set up engine should finger flip fairly easily (at least the sport engines, high-perf jobbies seem to be a litle crankier).
Ray - chilling the dough retards the yeast during the rise, making the bubbles tinier - gives the dough a finer texture which also helps make it flakier.
