I thought I liked the cajun red, but have since changed my mind. It doesn't do well with our equipment. That doesn't mean Cajun Red isn't good. Worked great for me over three days two months ago on Erie and Ontario catching 5- and 6-pound smallmouth, lake trout and steelhead.
Maybe your equipment sucks or there's operator error.
Trilene XL is good, tough, limp (for easier casting) and has held up over decades.
Vicious Ultimate Co-Polymer is good and won't break your wallet.
If you're not around much brush, Fatty's suggestion for 10-pound test is a good one. Ten or 12- will get the job done in most situations.
If you're around brush, weeds or stuff, you may want to upgrade to 14- to 17-pound.
