Actually, A low beam (about 33ft off the ground) with three elements would be far better then a dipole. The higher the beam gets, the lower the radiation angle. If you were using a beam up 60 ft then the skip would skip over the US into Europe or wherever the beam is pointing. Dipoles and verticals don't compare very well to beams. You may be heard with verticals, but beams give you gain making your stations S units louder. Your formula on the beam is wrong. For a 10/15/20 meter beam the minimum height above ground to be effective is 33 feet. Yes, verticals would work good for net control, but the net control station should be somewhere in the Midwest for the best propagation. Beams would work just as well. It's all personal preference. If you want, I can always help you out with CW. The reason I have reached 30wpm + is that I practice all the time. If you can already receive at 10wpm, start having QSO's everday at 10wpm. Your speed will quickly increase. You can read the article I wrote for NCJ (National Contest Journal) which gives a little bit of my CW story (as well as my ham radio biography) at http://www.arrl.org/ncj/2008/07/Darula.pdf It is a pdf file so you will need adobe reader.
