Doesn't really go in the Bits category, but this little jewel needs to be mentioned. I like hackamores for hunt seat riding, but it's almost impossible to find a mechanical hackamore that works with English tack. I bought this Beetle hackamore because I thought the short cheeks and skinny noseband might work with my bridle. Turns out this hackamore works better than I ever expected. The 6" cheeks give just enough leverage without being severe and the hardened rope noseband provides plenty of "whoa." I use this hackamore for long-reining and my horse responds to it nicely; lets me keep control without constantly tugging on (and toughening) her mouth. Technically it's Western equipment, but this hackamore crosses over wonderfully.
