I have the hfx hds on my faith and love them. However, I just ordered a set of el caminos today. I also sold my juicy 7s today (I think the idea of the power adjust knob is sweet, The juicys are really noisy, and i got a good price for them). I'm putting the HDs on my dirt jumper and using the el caminos. I hope they are all that they ar ecracked up to be. I was a little disapointed w/ my 7s.
