I'd like to add a few connection points to the deck lines. I'd like to maybe add at least one or two more sets. I tried just tying knots but didn't really like that so I want to add some hardware. I was thinking of just mounting them flush like at http://www.oneoceankayaks.com/Wshophtm/carb_hooks1.htm. Are there any other options?

What's a good place to buy the hardware from?
