Bang for the buck is Trilene big game. It's not the "sexiest" choice, but it is a good all around line. Little strechy but it's tough and forgiving. If you back lash, it stands up to the kinks. It's pretty cheap too. 15lb should do the trick. Don't get too hung up on choosing flouro, co-polomer, or braid. After you aquire more technique specific equipment, and gain more experience then start using different lines. Izor line is another good all around line, but it's hard to find. Mono still gets em in the boat. Good luck
