Hi Squall,
Personally, I would stay away from those invisa-leaders. Tryed one trolling for pike,12" 45lb test. Broke off, losing a pike and everything up to my main line. Yes, they are thin, but not very strong. Go with flouro. I use at least 20lb test. Make my leaders 2 to 3 feet long. Seagaur and P-line are good choices. JMO
