Whats best insulation undercarpet- layers or thick underlay

Hi,
Cant insulate under our draughty floorboard floor as too little crawl space. Am choosing between a really thick underlay 12mm Swaledale 54oz with 3.7 tog, or using 3mm Barrier or 5mm fibreboards in combination with 11 mm Cloud 9 cumulus.
Any thought on which approach is best?
