I'm not sure if they'll fit in the wheelpants you mention, but the "LYT" series from hobby lobby are good foamies. they don't deform easily like the dave browns, and they're generally half the weight, or less, for equivalent sizes. Price is irrelevant also, they're pretty cheap. I use the LYT60 in my E3D and Sport-e-stick kits. They're just under 6 grams per wheel whereas the dave browns in that same size are 19 grams ea. I know, it doesn't sound like much, but 14g per wheel more means an ounce more total weight, which is something to consider.
