^^^ All true, LeeD, and I am well aware of it. And I practice volleying three or four times a week - don't ask me how many hours I spend playing... ha ha!
But let me point out that you implied that heavy spin shots from the service line would be too slow, before your last post where you say pace is not necessary from the service line. Obviously I don't blast them as powerfully as I would from the baseline, only hard enough so that the other guy can't get to it or do much with it. I play enough mini tennis to be able to do that comfortably and without thinking. That said, if you have a system that works, great - that's all matters.
