Kind of hard for me to take the Sonic Arrow very seriously when it's so short and toy-like. The electronic beeping sound doesn't help. Blade bows have been done before in Rider, and Chalice did it better. :sweat:
Having been thinking about it...none of the Gaim weapons are any good. Gridon's hammer looks inflatable. Ryugen's gun is nothing remarkable. Baron's Banana spear is hardly much of a spear when it's so short and barely used for its proper jousting purpose. Even the DJ Gun looks awfully goofy, and especially when it combines with the Musou Saber.
I've narrowed it down to two:
1) Melon Defender. It makes Zangetsu look like a fortress, and I dearly wish we can see it make a grand return along with the suit.
2) Musou Saber. It's useful if you've locked swords with an opponent and your barrel is conveniently aimed right into their face. The only thing I don't like about the design is the ergonomics - the barrel of the gun looks a bit intrusive when you're using it strictly as a sword.
