Cooper 'S' brake pads query

Hi Everyone,

I've just acquired two new sets of 'S' disc brake pads for £20 the two sets,
and was hoping someone out there can confirm what I think they are, please?

First is a set of FERODO DS11, which also have LD20 on the box. ' Fast Road
' pads ?

Second is a set of MINTEX M1144, which also have MLB20 on the box. Racing
pads i.e. circuits ? Any good for hillclimbs/sprints ?

Thanks for any help.

Myles
