I have a Starboard carbon enduro for sale if your interested, it's pretty long at the moment but can always cut it down.
Let me know if you want to give it a go.
I rate the Coreban Hardcore, I am a fan of a bigger blade and am absolutely wrapped with the Carbon Kevlar Hardcore.
the quickblade peahi paddle would be worth a look. Towball & I both in love with the Jimmy Lewis peahi paddle which is modelled on the quickblade profile. Is a longer blade with lots of volume. I've given up on using the JL peahi version in the surf coz I keep snapping the blade at the narrowest point. Towball must be gentler coz he's had no casualties.
The original quickblade carbon peahi paddle could be a winner if you wanting to engineer powerful strokes
