The SS model length is the length in centimeters between the back of the band slot and front of the trigger mech. So,... the 130 model should indeed be 150cm overall.
I mentioned this quite a while ago, the webmaster fixed it, and I distinctly recall verifying that it was corrected. Just called the webmaster up and as far as we can figure - somewhere along the way, the server must have reverted to a back-up version since the page has remained untouched since. Really crappy situation and I'm sure both sides wish it never happened...
On a side note, the 130cm is a surprisingly effective size that is very versatile for its length! I originally thought it'd be way too long for use in murky conditions & kelp, but turned out to be quite nice.
However you work it out with Sea Sniper, I'm sure you'll be happy with the performance. My first SS euro gun was a 110. While the 110 is a great model, if I had one gun... it would be a 130 version so I could use it in open water as well as the kelp!
Of course, I'll be using the Marwan solution - just get one of each.
The shaft lengths Marwan mentioned - one of the reasons that euros traditionally have the "40cm longer than barrel length" rule is to counteract the sag. Picasso actually uses 50cm! The extra overhang on a supported shaft(like railguns or wood guns) just add extra drag when tracking. Also, since it's not used to counteract sag, the front section lists downwards slightly. The SeaSnipers have a shorter overhang to find a balance between aiming ease and reducing unnecessary overhang.
On a similar note - with larger wooden guns (like Wongs, SeaSniper Customs, Alexanders, Merlos, etc), most strive to have the threading for the shaft start right past the muzzle. Less overhang equates to quicker tracking and greater efficiency. Riffes don't follow this mentality because their slip-tip design requires a considerable amount of overhang. Wong, Mori, Kitto, & Aimrite slip-tips don't have this "issue".
Good luck with everything!
