Breeze will effect ground strike, spinning slash, and steel cylone(also savage blade if anyone really cares).
Aqua will effect Cross Reaper, Spiral Hell, Ground Strike, steel cyclone, and decimation, but since snow already covers all those things except decimation, and you should never be in a position where you have to use decimation, theres not too much point to bothering with it.
If you're looking for a gorget to get after snow, look at what other jobs you might level eventually. Spinning slash is covered by both breeze and thunder, so its up to you which organs you want to collect. The other big weaponskills affected by breeze are dancing edge, slugwinder, and blade: jin, while the ones covered by impaction are raging fists, dragon kick, and blade: jin.
edit: Playing devil's advocate for a moment
Please give me one situation, post 60, where having sword, axe, and great axe capped will benefit your party in any way.
Well as for axe or greataxe I couldn't honestly say since you excluded skillchains already(plus I agree with you on that end).
I can think of one reason, but if its an option you probably don't need to be reading this guide. Edited, Nov 9th 2006 at 4:23am PST by ArchangelLBC
