Is your 430 an NP mast?
Your new Excess is designed to work best on an NP mast. i.e. a mast that is about 14 - 15% bend - stiff in the bottom, soft in the top.
The Sailworks sails are designed for 12% bends (or they used to be). If you use an NP mast with these they will rig with more guts than designed. The Hucker is already a gutsy design so it might not suit.
The Retro isn't suitable for the waves because of its low foot and tube battens. A good washing would break it. Just looking at the Hucker specs I see it has 3 tube battens too - not a wave sail. No doubt its a super bump and jump sail though.
If you have an NP mast I'd be looking at sails from NP, North, maybe KA, Gun - definitely not Gaastra or Maui Sails.
Have a look at these pages for mast compatibility info. This site is a rare gem.
