With the use of 'super slippery' mast tracks/slots, etc. its 'easier' to raise/lower a main when going DDW. The problem is friction from the slugs/mast track and the friction of the sail against the rigging. A good way to keep the friction down low is to keep the sail material OFF the rigging wire when raising and lowering when DDW.
