Thanks!
Unfortunately you are only allowed two lines per person when in the "main basin of a Great Lake". Most of my downrigging will be on Sudbury lakes and the North Channel (Manitoulin) and Georgian bay (If i get out that far) which means I'm limited to 1 per person. The plus side being the rainbow limit in the North Channel is 5 per person!
I have been debating upgrading the downriggers to ones with 4ft booms eventually...
