Hi all. Just started Salmon and ST fishing this year. I bought a Shakespeare 11ft 8/9wt switch rod. Have bought running line and a Maxcatch shooting head at 24ft 600grain after reading this would match the rod elsewhere. I have since read on older posts in here advising 450grain for the same rod. Any advice on what grain shooting head I need. PS will be skagit casting. Cheers in advance.
