Excellent service from WWTCC - Paddles made and send from Germany and I was kept informed throughout.
Thought I would leave some additional info as testimonials were fairly thin on the ground when I was looking at these.
Based on one use at a local Mill, No proper WW rivers yet so take this with a pinch of salt.
The finish of the paddles is fantastic as you would expect at this price.
The 200cm Ergos Small Blade with Vario split feel a fairly heavy when out of the water compared to my previous 100% carbon cranks however when in the water they feel very light and buoyant.
I was paddling with 30 degree blades before but with these I seemed to have settled around 45 - 50 degrees as the optimum feather with the Lettmanns. Think it must be down to the blade being a couple of cm froward of the knuckles....... maybe.
The hand position on the crank is really nice and you can definitely feel when the paddle is correctly orientated plus the length of cranked section means you can play about with how far apart your hands are.
The blades shape is more long and thin than fat and wide and although slightly smaller in surface area than my previous set of paddles they seem more powerful and the power seems to come in earlier in the stroke and continue for longer. Guessing this is down to the paddle blade being offset from the hand.
The Vario joint is really nicely done and the flick switch lock works well. This gives 8-10cm additional length and infinite adjustments on feather.
The blades have a reinforced edge so this should help with wear.
All in all I'm very impressed - pretty expensive but hopefully they will last a long time.
