Do most people really dap with the rods? I think actual casting is a very important part of tenkara and hardly ever choose to dap.
FYI I haven't read the article yet, but I find the consistent misconception on the part of many fly anglers that tenkara is just "dapping" quite regrettable. Don't knock it till you've tried it!
I also hardly ever dap, this is usually something I only do in very tight
quarters where I don't have room for a backcast, or even quite enough forward room for a roll cast or bow and arrow cast. It also seems that many fly anglers have decided that fly fishing without the ability to cast long graceful loops to be intrinsically less rewarding. I enjoy western fly-casting too, just as much as I do tenkara casting; it's just different. With tenkara, where I have the room, I cast my line on a very steep plane using a short casting motion so that only the fly and tippet land in the water. I think a lot of other tenkara anglers do this as well. It allows you to achieve pinpoint accuracy and cast to targets in pocket water with impunity, achieving long drag free drifts. The whole experience of fishing with the ability to put your fly exactly where you want it within inches, and then not to have to worry about drag, is just plain fun. I often get distracted from fishing and end up seeing how far I can push the envelope with casting "target practice" just for the fun of it.
