On my SX the spinaker block is mounted to the comptip and my chute is slightly bigger than that of the Tiger. I have never dumped the main while flying the chute as that usually wont save you from the drink anyways. Bearing down is the way to overcome that when flying the chute and a hull. One thing Charlie Ogletree (made my sails) told me was to make sure the downhaul was off when flying the chute as he feared that would lead to mast failure. I have a large square top main and I have been waiting for the comptip to fail but so far it has held up in up to 25 knots of breeze both upwind and down with chute. But I am not waiting any longer. I got a good deal on a used Tiger mast and am working to have that rigged up for next season.
