i too prefer cloth surrounds or just pleated paper, but there are a lot of amazing drivers from the late 70's that used foam surrounds, mostly a manufacturing choice(not sure why),sadly most of them just crumble by 20 years or less
i have reconed many speakers and changed many surrounds anything under 8 inch could be done without shims in the vc , the larger ones need shimming to prevent rub
the key is patience,and the right tools ,appropriate glue,cleaning materials etc and doing this is very satisfying as you can get some very good speakers for nothing
as for surrounds ,there is a difference its the thickness of the foam and also the internal curvature of surround as when its glued back at an angle you need to avoid small creases and places that the glue does not hold properly
some surrounds are glued from the back of the cone.
for most of the Scandinavian drivers of yore i prefer the European foam suppliers,for the American drivers there are many us suppliers
i learned this the hard way as some of my refoam drivers would raise the spider and some were too thick and altered the fs
so research and have fun
for European drivers my favorite place is linked
Silence is golden duct tape is silver
