Lengthening speargun rubbers???
Got a twin rubber speargun I've been thinking of slightly
Modifying, I can just get the first rubber set but the second rubber is a constant struggle to get on so have been thinking of lengthening it by about an inch.
How much difference to the spear velocity do you think this would make? Basically it's no good now either I gotta take steroids to load it or modify the thing or sell and buy something more manageable.
