Fire line! For bass fishing I alway's use fire line. I went back to using triline mono after using fire line for a few years and it felt horrible. When you use fire line you feel everything and get awsome hook sets. Mono is good for surface lures because it floats really well but I can't think of any other reason I'd use it. I use a pline flourocarbon leader for peace of mind because I fish lakes with really clear water but it's probibly not needed.
My name is Fraser and I picked up fishing about 6 years ago and have been hooked ever since. My favorite species to fish for is smallmouth bass and lake trout but I really like catching every thing. I've made some attempts at catching musky but havent even seen one yet. When I first stated I didnt know anyone who fished, but as luck would have it most fisherman are more than wiling to give a helping hand. So through the fishierman I've met and still meet I feel like I've learned a great deal about the sport. In fact thanks to forums like these there doesnt seem to be a problem that I cant solve. Good luck with your fishing everyone and hope to talk to you soon.
