Time for New Line

[SamRiley]

My Cortland full sink clear intermediate line has had it and I'm looking to upgrade. What would you buy and why? Full sink? sink Tip? Brand?
Many thanks

I just bought the Cortland 555 Little Tunny. I've only been able to get out and use it 3 times but I really like it so far. It's very much like a Wulff triangular taper, int. sink, that I used in FL this past winter. It was well rated in a review of fly lines that was in one of the magazines I get.
