Cyclone slayer upgrade question

Hi,

I have this cyclone build in the current League.

https://www.pathofexile.com/account/view-profile/poganyz/characters?characterName=Buh%C3%B3estOfTheGordos

It ain't much, but it's honest work.

My question is, I finally got the currency (10ex) to buy a decent weapon, but I'm not quite sure, what the best choice is.

I could get a roughly 700 pdps Exquisute blade

Or a slightly higher (~730) pdps generic 2h sword

Or a significantly higher (~790) pdps generic 2h weapon (axe, or mace)

My question is :
- Should I stick to 2h swords, or is it recommended to switch to 2h axes (I see more people using 2h axes for cyclone builds, rahter than 2h swords). It's not much of a change in terms of skills and gear (only 3 passives, and 1 jewel synergizes with swords).
- If I stick to 2h swords, should I specificly look for Exquisite blades, or can a generic 2h sword outperform them (with like +50 pdps) ?

Thanks for the suggestions, in advance !
