I am wondering what the effect of a bigger wing like the infinty 99 or moses 1100 does for smaller vs bigger riders in light wind.

I am freeriding and like to use as small a sail as possible. 8-12kts on a 6.0 and infinity 76 front wing, 65kgs. I think the stall speed is like 7/8kts for the i76. I have seen foilers 90kgs plus foiling in light winds on the i99 or 1100 front wings with huge success.
Interested to hear what benefits light guys like me get from the super large front wings( i99 or 1100)
My goal would be to either be able to use a smaller sail in the same wind or get foiling in even lighter winds

I'm not racing or into hitting high speeds, just want to cruise around on a small board(wizard 105) in light winds with slow arcing turns or ride down a few small waves. Don't mind pumping around with very little sail power for a few hundred feet. From what I find the i76 is not the best wing to pump but sorta works, that's probably the only thing it doesn't do super well.
