I'm wondering, how much drying time is actually saved with a 1400 or 1600RPM spin? Our Speed Queen top loader is a relative snail ("fast" speed is 710RPM), yet even our heaviest bath sheets take only 40 minutes to dry. Regular clothes are done in 25-30 minutes.
At some point the faster spins won't remove any more water from your clothes, they'll just wrinkle the heck out of them.
