So what are we all using?

whiteclaw,

i'd really like to hear how the skips are constructed at the pivot points, mainly those at either end of the spring.  i think this so important and not enough is said about this.  the powerisers/rizers have brass bushings that  squeak/honk and wear through rather quickly (mine wore completely through in 2 months.  the 7 league boots i understand have bearings which interest me greatly.

thanks for your contributions here
