haha Matthias, you made the same mistake as I did (replying to a spammer that copied an earlier post).
Thanks, I feel less dumb now
but ok on the topic..I'm a big Guns fan but with Slash. I think Guns without Slash is almost like X Japan without hide. The main differences are that Slash is ofcourse better known for his guitar playing and in Japan the image is often cute instead of cool/relaxed. So, I haven't seen much of the new Guns. I knew that Dj Ashba could play a few notes but I underestimated Richard Fortus..he has his own way of playing and does it with a lot of feel. Sugizo could learn much from him. I like that Fortus plays Knockin on heavens door in a different way then Slash and Izzy did. The vid you showed about the James Bond theme is less impressive. I prefer the Godfather theme of Slash.
Like Sugizo, I think Fortus isn't great for power metal. If X Japan would play more power metal Panther would definitely be the best but for the slower stuff with more improvisation Fortus would do a good job. Better then Sugizo for sure. Only the image of Sugizo suits X Japan more but that's just my opinion. For popularity in the US Fortus might be better in that as well.
