Round nose Sponson help!

20131002_173112.jpg So I've been riding stand ups for many moons and I now ride an 04 sj with all your standard bolt on goodies and footholds. The ski has been amazing as far as power, stability etc etc for the last couple years. I recently decided to step up and add some front sponsons that I ordered from tom21/#zero
That everyone raves about. I glassed them in perfect and smooth and they look amazing. After putting my ski in the water I can practically lay the ski on its side and turn and it hooks up amazing... The carving is like never before. My concern is that I basically can't ride over 30mph now without fearing for my life. I use to be able to play in small flat water areas for awhile and then take off across the lake cruising 40-50 mph without a care in the world in search of every cove around. Then when we go the river we play around and also cruise up and down river at constant speeds of 35-40mph... Now as I pass about 25mph I feel there is no total control.. The ski will grab left and grab right as I'm just going straight and eventually buck me off.. Its like a white knuckle experience I've never had before.. Did I just inherit a problem with the tubbies, or is there something that can fix this? Has anyone else used these same sponsons?

Ahhh the tubbie wobble. Wide open you're fine and slow speeds you're fine. Don't do 25!! They all wobble at cruising speed. You have to adjust your feet and your weight accordingly. You've changed the shape of the bottom of the boat drastically and the handling characteristics will follow.

Spend more time riding with them, you'll learn to love em.

If you look close while riding fast, there not even in the water...my theory is unless your rear bond rail is cut out, the water hitting it forces causes the wobble from side to side.

Yip...I notched my rear bond rail & the ski runs perfect....watch where the water hits teh bond rail...you'll see it if you pay attention to the rear of the ski
