About Kahler 7328 bridge, it keeps guitar perfectly in tune and for those who doesn't use tremolos it can be also easily blocked, with allen key and one rotate move of your hand you have a blocked bridge, voila!
To explain, everyone could even buy Agile and then trade it for Perihellium, because in Europe we don't have 8string guitars with scale longer than 27" (maybe some luthier guitars, but I don't have a time to wait for it).
Yes, 828 would be great (especially in natural finish), but the best way for me would be if someone lives (or has someone) in Europe. Is there somebody from Europe?
