Thanks!
I keep my chlorine level between 8-10 at all times. I also shock it after a couple of days of heavy rains, especially if they're hurricane-driven, and at the end of a week of heavy bather load (my house is the place where all the kids on the street hang out all summer).
I use the best guess chart (link in mine and Watermom's sig) just like we recommend to everybody else. Letting your chlorine get below 5 or 6 with high CYA will result in an algae bloom, and it takes a LOT of bleach once that happens to get it up to shock level, but if you never let it get below 6 to begin with, it's not a problem.

As for comfort, like Watermom said, higher chlorine with higher CYA feels exactly the same as lower chlorine with lower CYA. Any discomfort is usually caused by letting your pH get out of whack, or letting CC build up without a shock.
