So, I'm looking for a new speargun to use for hunting large fish (Grouper, king mackerel, large trevally). I don't care much about the price, just as long as it's really good quality. I'm thinking about getting one with a cuttlefish design so it's easier to travel through the water with. I wanted to get the Riffe marauder but when I went into the store it's too heavy for my liking. Any suggestions on what speargun I should get? I already have a couple of rob Allens (700, 900 roller, 1200) and a Riffe euro.
