Actually I took a look at that link and it says that the size 90 has 4 bb, but the rest, in the main body, have 7+1.

Btw, which would you say is better (overall warranty and other things included) is best: the induron or a catala both in 400 size? Mind you, I paid only 89 for the catala brand new but I am wondering if it is worth paying 20 more to get an induron.
