What length 12mm dynamea rope will fit on a standard low mount winch drum
I am looking to upgrade my Dyneema/SK75 rope on both the front and rear winches to 12mm for a little bit more safety margin. Currently running 10mm and get 30m of rope with the drum being as full as you would want. I see there are 25m x 12mm ropes and 30m x 12mm ropes on sale - from the Dyneema Shop, just dont want to waste/pay for 5m that will end up on the floor x 2.

I know @MB is a big fan of the Whitlams Brand, just unsure if these above are genuine or the Whitlams brand is the deal and certified load rating. $ are not the focus, just not wasting the $ by buying the wrong length is more the issue.
There is also another brand called Spydura which is highly rated. 10mm Dyneema - genuine has a breaking strain of close to 24000lb, the Spydura a touch higher.
