At 40' they will rock!
The hamsticks are tunable, so you don't need a tuner. The buddipole uses coils to match and a tuner is a good idea to trim out the last bit.
Just always remember when deciding on an antenna: To make it shorter than a half wave dipole, something has to be sacrificed, usually it is the wattage of the radio being given up as heat, and usually in a matching network of coils. You always have to make the decision of what you can live without. I sacrifice 2/3 of my hundred watts with my Chameleon to get portability, and half my power with my end fed. The math never lies.
Now for the good side: You can do a lot with just a few watts on HF if conditions are good. I worked a station in TN from SC with the 500 mw exciter output once, forgot to turn on the damn amp. Now I rarely go over 50 watts because I know my antenna system is putting out 90% of my power. The reason compromise antennas work is because the 10 watts you get out of them is enough a lot of the time.
I routinely do work at a TV station that has a 400,000 watt ERP driven by 18,000 watts up the 2200' long, 6 !/8" hardline. With those gain numbers, a small percentage of loss at the bottom will make a huge loss at the top, and more importantly, a huge reduction in field strength which can relate to lost revenue because people just can't see a picture. The point is, without a system that is matched well with small losses, throwing watts at the problem does little to fix it.
Whew. Guess I was overdue on my antenna rant for February.
