And further..... The Naish blades are the reverse... Massive area.... Please explain.

Yeah exactly, I like the qb 100 size.... But wanted to know the Starby eq. Sounds like the 550.

It's almost like the early days of kites.... Projected area v's flat area.....

I think.. lol

I've got both the QB Kahana 100 & the Starby High Aspect 600 (93sq in.). I personally prefer the Starby but when you put the two side by side the surface area is not much different, suffice to say the high aspect is longer and narrower in the blade design and QB wider, shorter and slightly bigger surface area. I had a look at the two smaller high aspect paddles and imo they are to small. I suspect they would be more suited to small women or children. I saw an interesting video from Danny Ching, he believes in a larger paddle and if you want to up your stroke rate you just don't put as much blade in the water. When you want power you then have enough blade size to bury when you want.

Its interesting, there appears to be a swing to smaller blades in Sydney, compared to qld. similar sized guys running two sizes smaller.....

either way the speed seems the same. they r all quick.

Im going 100.
