Hey guys, I'm completely new to spearfishing and I'm starting to buy some equipment. I will be fishing in Costa Rica so I bought a speargun (90cm) and a reel for it. The reel comes with 50m (around 170ft) of black 2mm nylon line. Question is, considering Costa Rica has quite a rocky bottom, and groupers/snappers tend to hide under these rocks, would you consider that the nylon line would be insufficient to withstand some rock abrasion? Should a dyneema be a better option in that case? I would still get my mono to the spear and the reel line. Any suggestions?
