you didn't mention the boat but I will assume you have a modern prebend mast.

Start off in light air with downhaul at just enough tension to take wrinkles out of the main. Once you are able to double trap and have the boat popping up too quickly, begin inching on some down haul to control the power. Once you're in the ball park, have crew play the main while trapping to fine tune the power during the gust. The goal is to ease at gust onset and then start sheeting in again BEFORE the lifting hull reaches its max height & starts to fall. You want to keep the hull off the water. If the crew is needing the sheet more than an easy arm length of line to control the hull pop...you need a bit more DH. If the hull stops lifting/boat feels dead...you've got too mcuh DH for current breeze.
Steering up to control the power is not a go fast technique...but it can save your butt is an emergency (ie if crew forgets to react on the sheet).

This technique will make the boat feel like it is on rails...no longer popping up rapidly...squirting forward in the gusts. It need practise, but when you get it right the rewards are big.
