Thanks for posting that. I was thinking of getting a spear 5-10cm shorter (e.g. 120/125 vs. 130cm) & thinner (6.3 vs. 6.6mm) for my 90, so good to hear it works fine for you. Long ago I asked Rob Allen-- as railguns are reputedly more tolerant of different spear length as they don't suffer spear droop -- & he reckoned better not to go more than 10cm shorter, although gave no reason why. Perhaps due to aiming...

Unless you sight alone the side of the barrel SA-style, as advocated in Len Jones book. Easier if, like the RA railguns, you have no loading butt blocking you view of the side of the speargun.
IDEA: maybe they should make loading butts so that you can positioned to suit your aiming style - vertical for side-aimers, horizontal for top aiming.
