I use my low / high rate setting only on a maiden. I dail in lower rates and also higher...I take off with low rates and if I feel it's too little input I switch over to high rates immediately. After the maiden or second flight I switch to high rates. Whether that be 100% rates or less. My Edge at the moment are set too 85% on high rates. This is my comfortable flying rates. It's not too twitchy and not too little. I will up it in a couple of more flights. I do however have set my "low rates" to 85% aswell, since I have found numerous times that I by accident knock the switch.
