kool-stop brake shoes for single pivot brake

i have an old dia-compe single pivot front brake--the kind you see on
all the old steel road bikes. anyway, i'm overhauling my bike and was
thinking about replacing the brake shoes with salmon kool stops. the
originals still have a good amount of life in them, but all the talk on
here has got my interest piqued. so i looked at the harris webpage
(http://sheldonbrown.com/harris/brakeshoes.html) and the shoes i have
right now resemble the kool stop continental (about 1/3 of the way down
the page.) but the "mountain salmon", "supra" and "eagle" all look way
niftier--can i use those on my brake? they don't have the metal holder
thingies like the shoes i have right now, but then neither does the
continental.

i use fenders, if that make any difference. also, this is for my fixed
gear, and it's the only brake i have--so i'd like it to be pretty good.

thanks for any advice!
