Welcome aboard, Jim. I 'm also trying to get my code speed up. Ebook2cw does a nice job, but lately I have been using Fldigi to make practice mp3 files to take along with me on my walks. Fldigi creates beautiful cw from text files. I also find the iCW net on Saturdays to be a great source of QRQ practice.
I too am always looking around for a display case for my keys, since I usually only have 3 or 4 on the operating table at one time. I have decided to go for it with single lever, and now a Begali Sculpture Mono is on the way to me at this very moment. I have his Simplex Mono, and I like it a lot, but there are some things that aren't quite right and it seems like they affect my sending. I am hoping the simplicity and precision of the Sculpture single lever will provide for easier sending at the speeds I want, with much greater accuracy. I don't really care about sending faster than 35-40 wpm at the most, and most times around 33 wpm is fine, but I want to be able to do so accurately and without great expenditure of effort during long rag chews. I can send fine on a bencher and similar, but find that as I go up in quality the effort to send good code goes down, and proportionately, so does fatigue during long rag chews.
I had meant to say also, that faster than 35 wpm on the paddle, the preferred sending device is the keyboard, and I don't really have an interest in using hand devices to send faster than about 40 wpm. I don't know if that will change in the future, but the art of conversation with The Morse is best served by the keyboard for me.
Thanks for the note. I will be silent for a while, trying to learn what this is all about. I am not quite sure why I joined, other than looking into something new. I will likely be the least prepared member. I am sure I will have to investigate keyboards in the future.
