D'oh. I just rechecked the club rules and I misread it. For boats my size it is 1/2" minimum. Well, that settles the size issue.
Thank you guys for the tips on the lengths.
3-strand, I can splice myself, it's cheap, it gives a little.
Any pro's to choosing a braided line (other than it's nicer on the hands)?
I'll likely forego the snuffers if I'm getting space at the club since it's got no surge at all and the docks are floating.
Lastly, quality... What do I look for when determining quality? I assumed 3-strand nylon was more of a commodity product and had intended to buy wherever was least expensive; Now you have me thinking I need to be more selective.
