It increases speed. Do you find the flare/fade easier at higher or lower speeds? Higher speeds require faster reaction from you, and decrease precision. Like everything else it's a compromise between extremes.
Do you prefer a frameless kite? A vented Rokkaku can be adjusted for it AOA. A normal ROK can but don't think above 30 kays would be sustained for a duration of time. I've had my ROK in winds about 35 but I didn't feel comfortable pushing it. They would lift a KAP rig too. I think that you can buy them "off the shelf" from Jones Airfoils but not 100% sure.
To some ears, silence is golden
Other attributes may be in part kite dependent, and you are encouraged to experiment. Have not tried it on a Quantum myself, but here is a snip from the Prism manual for the Zephyr -- while it is a lighter wind kite you may find some similar results. (The effects may or may not be subtle.)
