Airgun length? Help

Gecko is spot on about the shock absorber. You can use an 8mm spear in the 55 Vuoto if you change the shock absorber - or use a diameter modified shaft tail end (connector) on your 8mm shaft instead of the standard. An 8mm "free shaft" (front tied shaft, no connector) can also be used. You should increase the pressure in the gun if you use an 8mm spear (go to 26 bar). You will still be able to load it with out trouble as the 8mm shaft is less flexible. You can start with the standard 55 or 65 vuoto and see what you think.
The 65 vuoto would in my opinion be a more "all round" choice especially because it also has the power regulator and a better aim for longer shots if the viz is good.

(I would chose a 55 pneumatic with 8mm shaft with exchangeable spear tip (vacuum barrel, or not) and reel, if low viz, seaweed and carps were my speciality. But I must admit that it's not. So that recommandation comes from my reading on East European forums - not own experience :) Hunting lakes and rivers are not legal in Denmark.)

the non Vuoto probably requires less maintenance. The shaft will less likely bend after hitting the bottom. 65 fits in most regular luggage and it is more useful in the ocean. since the the line wraps 3 times you probably get 60 cm extra reach. I really do not see how the 55 would tangle less. I'd get the 65 non vuoto, the gauge (useful if you want to pump more air in or lower the pressure at different times), some spare tips, spare shaft, spare loader and spare shaft spring / ring. Those are easy to lose, and without a $3 loader it may not be possible to safely load the gun. If I go in shallow water with jetties / rocks I do not take the vuoto but the regular predathor.

Thanks for the help fellas. I finally placed the order so I can put this subject to rest for now.

I chose the 55cm vuoto special edition. I really wanted the power reducer, but that meant buying the PLUS model and getting a separate dry-muzzle kit. Which would have costed me an extra $100. So I decided against it. I'll be kicking myself after bending my sixth shaft lol.

It sold for $400 at canadian retailers, but I found the thing for $140 from an italian shop. I just hope that customs go easy on me.

I'm quite eager to view and document it's performance. Some of you think that i'm foolish for getting the weaker 55cm model and I can understand why. So a few fishing trips are in order to see who's right. And If I enjoy this hobby well enough, i'll simply buy one in every size. So i'm not too concerned about my choice. Time will tell.

Thicker shaft of non vuoto does not bend as much as the thinner vuoto's.

Anyway I would buy with the order a spare shaft, a couple of spare speartips and spare loader. Those go for $3 to $8 each. It does not increase the cost of shipping by much, and in North America they are more expensive or take longer to find (you can order them on ebay from EU sellers). Nothing ruins a dive like losing or forgetting a snorkel, a loader, a tip. I secured the speartip with electrical tape, the screw tips sometimes may come off even if screwed tight.
