I had a Bark Laird 14 for a few months and I weigh 100+kg.
ActionSportsWA is on the money with how it goes.
On medium+ condition Dwers there are times when you get your weight fwd to catch/maintain runners and footwork is required to keep it steady due to the narrow rolled section thru the front of the board. At the end of these runs where fatigue is an issue is when this board gets a little squirrelly.
This is not a bad thing, just high maintenance and good for your skill set long term.
I only parted with mine for financial reasons to get a DW specific board. I would have liked to have kept it as it is a fantastic all rounder that anyone can paddle, making it great for first timers and family.
It was brilliant in light conditions, especially lake/estuary dwers where its flatter rocker and knife bow suited the smaller period and straighter runners. I also used it for flatwater training as its great glide was good for concentrating on stroke technique.
I do miss mine but the boss said it had to go for me to get a new one.
