In the beginning of the time when these kind of ultra-light rods spreader in Japan, many anglers broke the tip, because this rod has a little bit special character on action.
To feel the small touch of biting, this kind of rod are made with specially-fast action.
ZENAQ ASTRA 68 and S76 Accura are the standard model of Mebaru rod.
As you can see on picture and the link, even 400g weight bends the rod with acute angle.

On this picture, the rods are fold by 45degree from the parallel.
If we stand the rod more, the tip might exceed the limit of its standings.
Mebaru and Aji is smaller fish than Breams. We call “Big” if the size becomes over 25cm.
So if we use these kind of rod for breams, we have to be really careful.
