I would advise you to check if your clutches will accept a line one size smaller and if they will consider going with the smaller line. I used the same size and with VPC's low stretch properties feel like I could have saved some weight aloft going with a size smaller and still had less stretch than with lower performance line.
I plan to replace my jib halyard with VPC this winter and I for sure will go one size smaller on it assuming it works with my clutches.
