[High-Speed-CW] Best type of paddle/electronics for high speed

[Paul F. Sehorne]

 Is there any consensus among the high-speed group as to the best 
paddle/keyer types; i.e., dual-lever, single-lever, bug, no keyer, 
iambic, etc.?
I saw at MorseExpress <http://www.mtech.whsites.net/schurr/> a reference 
"...the Einhebel is possibly the very best single-lever paddle in the 
world.  Designed specifically for European-style high speed 
operation,...".  Since there is a high percentage of European callsigns 
on the HSC, VHSC, SHSC, and EHSC I'm wondering if there is a common 
thread regarding hardware/electronics.

I've been a ham for many years, have always liked CW, but have never 
gotten serious about high speed until recently.  Whatever advice you can 
give me, particularly regarding keys, bugs, paddles, etc. will be much 
appreciated.  I can copy individual characters sent at (Farnsworth) 40 
wpm character speed and 5 to 10 wpm text speed almost 100%, only having 
a problem distinguishing between S and H, and H and 5, and a couple of 
others that have three or four dits in a row, like V and 4). I can also 
copy W1AW code practice at 18 wpm 100% and decreasing from there to 
about 75% copy at 25 wpm.

Thanks,
