At the momment i have a 110 OMAR Excaibur with 18mm rubber.... i am more than happy with it and want 2 contine to use it but want a second gun for out wide.... I have being reading up on SA railguns and am thinking of going that way, but any help on way makes i should consider would be great... I want 2 target large pelagic's with the new gun...... Most of my diving is on the east coast of Austraila
