Noob: Question about Continuous Ridge Lines

[Billiard Pete]

Hey guys,

I am getting a Warbonnet Super Fly. I think I want to use a Continuous Ridge Line (at least at first). I live in MA and will most likely camp in the area and surrounding states only.

So to my question, how long should I make it? I think 50' is too long, but 25’ doesn’t seem right either (but once again, Noob).

Thanks, Pete
