I mentioned I have a bent-shaft all-carbon Camano, which is the Perfect paddle on my little Kestrel.
I also have the glass-blade, straight-carbon-shaft Coryvecken, which is the Perfect paddle with my T160.
They weigh almost exactly the same within an ounce.
There's $200 difference between the cost of these two. I found my Coryvecken for $220 at outdoorplay.com with an added coupon discount bringing it down to $200 with free shipping, which was a no-brainer purchase.
If you can justify the $500 for the bent-shaft all-carbon, do it.
The shape of the Werner fiberglass blade and carbon blade in the same model is identical.
The swing weight of the glass is a little heavier, which you might notice on a longer shaft, but if you look at one of these paddles, they're still quite lightweight.
