GKSI just use really long marine tiedowns. For my summer setup, I looped two around a fence post and I think it will give me good speed. Look up "marine master bungee" on Amazon

GKSeither 1/4 or 5/8, I honestly forget. you will need at least two though. I use two and I only weigh about 120 pounds. I got 2 30 foot lengths.
