CWW: it came with a 7mm shaft. for the time being i cut 2.5'' from each end of the band, thus i reduced it by a total of 5''.
Mr.X: im positive its 16mm. when i got home i took out my calipers and measure everything. i have the RA chart that shows gun lenght and suggested band length along with a step by step tutorial to tying constrictor knots. i tested the gun last nite at my friend's pool, and with a single wrap of mono the shaft droped 4 inches at the target which was well within the gun's range, and we also tested some of our other guns and they didnt drop one bit.
hopefully wednesday after classes il be able to get out and test the picasso 110 with a single 18mm and my new 130 after modifying the bands.
****note to self: cutting rubber is a bit*h***
attached is a pic of the gun previous to shortening of the bands.
