If using a CRL there's no reason to use two Wasps. Better to use a Dutch Hook on one end and a Wasp on the other. Use Tato Gear Tarp Connectors or prussics for centering the tarp on the CRL. If using a separate line off each end of the tarp then Wasps, Stingerz or Flyz on each end work good.
The Tato connectors work better with smaller cordage.
