Maybe I am just looking inthe wrong place, but looking at the spycor web site, FL is $.59/sq foot, MS is $.53/sq foot, and platon is $.49/sq foot. For my project it would only be a $51 difference between FL and platon. Hardly double the price.
Maybe pricing is different where you are.
Where DeltaFL and DeltaMS are available in store:
$170 - roll of MS (6.6 x 65.6' = 433 sqft) = $0.393/sqft
$70 -- Roll of RL (3.5' x 30' = 105 sqft) = $0.67/sqft
Though it depends on if you can buy in the biggest quantity roll without too much left-over.
For me, I measured exactly how my roll would go and I am very lucky because I end up with only 30 sqft left-over.
