Shawn You are what we call over here, a real stinker! Its Friday and I am not less than 5 hours ahead of all you guys and now I will have to spend the entire week-end wondering about the true answer. My shot will be Calcium Chloride time because of the De-ionised water, then sucrose unless the water is hot, then the diluted anti-freeze. I haven't a clue as to why, just gut feeling. -- Regards Graham Naisbitt [log in to unmask] Golf quote of the week: If you watch a game, it's fun. If you play it, it's recreation.
