I call 'overkill'!
Overkill is not bad on the one hand but it will come with extra costs.
I'd forget about the Helix mooring for now and get a used 350 - 500# mushroom and beef up the eye of the mushroom by using a new shackle that you have welded onto it.
A lot may depend on your local conditions; how much fetch you get from what direction(s), how soft the mud etc. The weakest link in the chain is always a problem so you could get new chain if you wanted.
We use what is either a 250# or 350# use mushroom mooring in the Hudson by the Tappan Zee Bridge (soft mud) for our 27' 7200# boat and we survived hurricane Irene (with extra pendants attached of course).
Chafing gear is just as important as the condition of your mooring.
How heavy is your 30' boat?
Still sounds like overkill to me.
Yes, it's over kill. My boat weighs in at about 10K lbs. However, I plan on getting a new (bigger ) boat before I get a new mooring The new boat may not be that much bigger, but it surely won't be any smaller. I would rather just have a larger mooring installed now.

The minimum requirement in my harbor for my boat is 500 lbs. If I get a 35 ft boat the minimum requirement jumps to 750 lbs.
