At the moment, you obviously need someone who has contacts with Caparison or Japan since they're actually marketing their stuff there and not just creating myths. From what I've heard though, the Caparison-picks that Evergrey use are similar to the Ibanez Paul Gilbert-picks, however they're not exactly like the pick you're using now but atleast you can get them quite easily here in Sweden. You can always try them as an alternative, but as I wrote earlier, this is just what I've heard, I haven't used any of those picks myself. I think the Gilbert-picks are somewhat thicker than the Cap-picks, the G-picks are 1.0 mm anyway...
