The tadpole is an awesome tarp and you won't regret getting one. The tri-loops are just another place to tie your lines to. I just tie directly to the ribbon that's already attached to the tarp. Some people like to have the tri-loops, but I really don't see a benefit. Perhaps some other will chime in and give their $.02.
You might want to start another thread asking about the tri-loops in the title (could get more views?)
