Can I ask if you thought the take off ground roll was longer or shorter than your 'normal'?
Somewhat longer but not significant, still used less than half the 1600 ft strip.
I tried it again last night with a heavy pax and used Silvaire's suggestion of being a bit firmer with getting the tail right up and it worked , there was a lot less skipping, however I wonder if there is a trade of when the strip has undulations which seam to be exaggerated with the tail is right up. Kinda catch 22 deal
