I have never heard of this gun - and i dont know whether there are 'specific' fittings for them.
You can give this gun a shot to see how it performs with the two yr old rubbers, there are plenty of affordable euro guns on the market with available spares and add-ons - save some money and treat yourself this xmas!
As for your Line :
You could use a 'bungee' - a piece of rubber to compensate on the length of the line , this also reduces shock when the shaft misses the target/fish.It also acts as a shock absorber when pulling fish back in .
I use a braided cord as a line , this is good because it has some give in it , i buy this in a local hardware store , its dirt cheap, and you can change it often.
I buy most of my stuff from apnea.co.uk . however there are loads of sources for spares.Its just finding them thats the trouble.
