How goes it!? I'm new to spear fishing. Just picked up a cressi comanchi 90mm.. I took It out for the 1st time last wk & after about 7 shots the mono came off of the crimp that was attached to my shaft. Is there a way to just open the crimp put the line back in and close the crimp back up? Or should I just buy new crimps? Also, my line floats around when I'm in the water, i bought a shock cord (I think that's what's it's called) with a rope loop on one end and a swivel on the other. I read that helps keep the line snug. How do I do that? Any help would be GREATLY appreciated!
