I think that if one of the players prefers a 90 sec. clock, then let him have the 90 sec. clock. I myself prefer 90 seconds. I usually get my calculation and shot off within 30-45 seconds, but there are situations, especially in UEL, where a little more calculation is needed. What's wrong with that? There's enough stress in life. Why add to it when we're just playing a video game?
Some players play 20-30 rounds a day. I can understand why they would want to play speed golf. They're after as many credits as possible. But those of us who play 1-3 rounds a day do so to have fun and relax.
