Why would you want a stiff rod like a CM Crest or SK4 to fish clean ground? Get yourself a rod with a bit of feel to it, something that will bend where you can actually feel the fish on the end rather than just bully it in with a scaffolding pole.
If you are looking at a Century then I can highly recommend the Tip Tornado LD for clean beach fishing with a bit of mixed thrown in. Very slim, lighweight, excellent bite detection and a joy to cast. I've put a 150g lead over 200 yards with mine, I've also caught double figure smoothhound from the shore with it. Brilliant fishing rod for everything except rough ground / kelp fishing.
