I would seriously dought any store in the country would stock that paddle. In buying for a WW shop for over 6 years. I have never had a customer request a 60 degree paddle, let alone a left handed 60 degree.
But, you may be able to get a Lendel adjustable breakdown paddle. That can be set at that offset. I know it is not the news you wanted to hear, but it is true.
When I started paddling in the early 90's I started using the radical 80 degree off set. Since the late 90's the norm has been 45 degree and less. It's just far easier on the wrists and shoulders.
Slalom boaters still prefer some of the higher offsets and that is why companies like Lendel, Double Dutch, and Galosport still offer them. But, few retail shops carry these brands due to lack of interest by the masses. Confluence Kayaks in Denver did carry Lendel, give them a call.
I love to dance, but who needs the music- It throws me off.
