Whatever you buy make sure that you do a couple of very simple things to ensure a good lifespan:-
1. Rinse in freshwater after each and every use in the surf.
2. Coil it up in loops to store.
3. NEVER,NEVER, EVER wrap it around your board and fins.
yes I expect comments about wrapping it around your fins, but I can tell you for sure that ifa leggie is going to snap it will snap where you have had it wrapped across your fins.
