[Amphibian]

The manufacturer pressure will not be the same in both guns i can almost guarantee it, unless you have checked this with a pressure gauge of course, in which case ignore me!

Did you mean you pumped them up to same pressure?

Also a 110 standard pneumatic will not achieve that much greater velocity or range than a 97, the piston as it pushes out water kinda reaches a 'terminal velocity', ok so the extra 13cm prob adds a few fps but not a lot of difference at these lengths (of course it's totally different comparing a much shorter gun!)

I too own a mares cyrano 970 and very pleased with it, my graphics were as per the second picture and i got the stainless steel shaft and a black one.
Managed to pick up 4 spare shafts (the naff black ones) for about £2 each brand new! (the joys of ebay) i did this because i expect to have a few bent ones in the UK conditions.
