Toggles are really there for grabbing when you are in the water - not so much for carrying. Be careful not to get your finger caught in the cord! A 'surf-wrap' will close this gap so you can't get your finger in there.

To carry your kayak put a hand under the bow, stern to fully support your kayak - do not have all the weight carried by the toggles or decklines - they are only as strong as a few plastic deck fittings or the screws holding them!
