I layed vynol flooring in our kitchen 4 years ago and the wife wants a new wooden floor.. I did put in a new sub-floor in before I layed the vynol to level up the floor.. Looking at the new floating floor with the snap together connections.. My question is should I go ahead and lay the foam down or just go right on the vynol flooring?? Height is really not an issue and the floor is level...

Thanks
