Sandtrout Dan, when I first started Tenkara fishing I began with a section of Level Line the same length as the rod. I feel this is a good starting point. Or a length of Level line about ten foot long really helps to show the fish a very natural delicate presentation with nothing but the fly touching the water. ......
D, Good to see your back posting, great info. Always enjoy your insightful posts.
Thanks aR. I've been busy with other life issues and I figured the forum could use a break from my odd rambling thoughts. So while still reading the forum I've refrained from posting much lately .
.... I ended up (at the advice of many) getting the IWANA 11'.....
Thanks again for all the info! DAN
Dan since I now know you have the 11ft ( 3.3m) Iwana, and as adventureR mentioned he and many other folks start off with a line about the length of their rod, then I think starting with a line about 11ft + 3 to 4 ft of tippet would be a good starting place. Or may be you'll find you want to go a little shorter, 9 or 10 ft before adding on the tippet, till you get the hang of Tenkara casting and landing a hooked fish.
Like me I think you are wanting to not waste line by ending up with pieces that are to short to be useful. Thinking about the 11' Iwana and how to make maximum use of 65ft of level line. I would revise my previous suggestion and skip the longer line lengths. You could get 2-11ft lines, 2 - 14 ft lines and 1 - 15 ft line. No wasted piece of line 3 to 6 ft in length which is kind of useless unless you have some other weight of line and want to make a hand tied tapered line.
Again I would not cut all of it to different lengths until you know what you like or can use on the streams you fish. I would perhaps start with two lines: 11ft line and a 14 ft line. Add on 3 to 4 ft of tippet. And try casting and fishing with them.
If you look again at the Ishigaki graph on the Little Streams video. You may note that the referenced rod length is 4.0m ~ 4.5m. He then list 4 lengths of line that are 4m, 5.5m, 7m and 9.5m. Or thought about in another way he shows lines that if referenced to the 4m rod the length the lines as a ratio or multiple of the rod length ( RL ) are : 4M = 1.0xRL, 5.5m = 1.375x RL, 7m = 1.75RL and 9.5m = 2.375xRL. I don't think most of us would try using a line 2.375x RL. To long and to tiring to cast and probably not useful most of time. ( maybe useful after years of experience on the right river )
For the 11ft Iwana a line length of 11ft + 4 ft of tippet = 1.379xRL, about the same ratio as the ratio of the 4m rod to a 5.5m line. So maybe try an 11ft line plus tippet. See how it works for you. You can always use a shorter tippet or shorten the level line a foot or two if you find you'd like it a bit shorter.
If you cut a piece of level line at 15ft and add 4 ft of tippet = 19 ft, the ratio to the 11ft Iwana is 1.75. The same ratio of the Ishigaki 4m rod and 7m line. I don't think you will want to try fishing with a line any longer than that with your Iwana. At that length it takes a little more skill to roll over the line during the cast and land the fly first and keep the line off the water.
The 19ft line with the Iwana should let you cast to about 17 to 24ft maximum range keeping the rod angle high, one o'clock angle. Someone mentioned on another post that some experienced fly fisher said that around 20 ft is the perfect fishing distance. And this should cover that range easily.
And of course a piece of level line 14 ft in length + 4 ft of tippet will get you an 18 ft line. As mentioned before Daniel has stated elsewhere that he finds an 18ft line to be a good all-round length to use. otoh, he mostly uses the 3.9m Ayu or Ito. An 18ft line on 3.9m rod has a ratio of 1.4x RL. But , 1.4x3.3m ( Iwana) = 15ft. Which brings you back to the same ratio as 11ft level line + 4ft of tippet on the 11ft Iwana rod. Which is more useful or easier to use - an 18ft line or using a rod/line with the ratio of 1.4xRL? Only fishing with the different combinations on the streams available to you will answer that question.
If using 11ft of level line, adding about 3 to 4 ft of tippet you should still be able to cast to around the 20ft range with a lower rod angle, two o'clock angle. Try this length and see how it works for you. Maybe you will find you might want to shorten it a bit to 10 ft or 9 ft before added a length of tippet. Then try working up to casting a little longer line. Holding the rod angle high when using a total line length of 15 ft you should also be able to cast as close as about 10 ft too.
Cut two pieces of level line: 1 14 ft and another 11 ft. Try the 11ft first, see how it works or if you want to shorten it a little. After some practice or some fishing with that length try the 14ft line. Only after that decide how to best cut the remaining 40 ft of line. Who can tell - you might find that 11ft of level line + 4 ft of tippet is the best for you. In which case, from 65ft of LL you can cut five 11ft lines and one 10 ft line.
That's about the best ideas I have for an 3.3m Iwana and how to best utilize 65 ft of level line. Maybe others with different experience will suggest something different.
