Have also heard they will reduce stall speed (logical) and damp the roll rate (also logical). My current 320 gets pretty sluggish in climb by about 15,000' in the summer (16-17,000' density alt) if I am loaded anywhere near gross. I would be very pleased if I could get comfortable climb and cruise into the high teens with these tips. Also, I'm debating whether or not it is worth the hassle to make them removable. I'm hoping one or more of you out there might have more hard data or could contact me off-list to discuss your plane with them. Thanks!
