My thoughts are get your self a Kialoa Methane..

The smaller blades do take a little getting used to but once you do you'd never go back.
The new Werner Nitro will be a little softer in the shaft (so I've heard) so they might be worth trying.
The new 8" blade Naish paddles are nice and the white blade model is a bargain price.
I don't know much about the QuickBlades but I'm sure they're another good option.
For me it's all about the 'feel'.. so demo first if you can.
