Combined with 9650's on the elevators and a 9155 on rudder, they are all plenty fast!
At my skill level (or lack thereof) it doesn't seem to be an impediment.
My main model now is a Caelestia with ATX 94774 (ail), 94761Z (el) and 94775 (rud) which are also pretty fast.
I hope some day to be able to afford some BLS all 'round, just for the experience.
