I just picked up a couple of halibut poles with longbeach 65 reels used for $50 for the pair. The line on them needs to be replaced one has mono and the other has a braided line of some sort. My question is what type of line should I put on the reels. I will be fishing 150 - 600 feet deep so mono is out of the question to much stretch. I looked the new stuff out their but it is expensive for a small spool. Do you put a backing on the new lines . What do all you guys use out their. I have halibut fished before but was on a guided trip and they supplied all the stuff. I am headed to port hardy for a week this summer and want to try a little halibut fishing along with the salmon fishing.
