personally always had hopes, i started with the old black and gold mini then went to black and gold M4's then to silver m4's now got the tech m4's.
excellent loads of power and on a silly rotor in the alps (203) i could go over the bars by feathering the lever!
initially we had an issue where an air bubble would get stuck in the levers, hope did a video how to flip the lever and bleed the air for us, we still had issues so sent them back to hope they bled and returned them.. excellent very happy.
My GF went from Avid to tech m4's are trying mine, she too had the air bubble issue and it was again fixed by hope, she had a long time of being not happy due to the air bubble issue but a week in the alps and she's happy again with them. (it was a first time over there and she did well) but dragging the brakes occasionally and they still lasted (the new hope material is excellent on resin pads the black version) and never over heated..
add easy lever adjustment and good feel.. my fav brake. plus hope are excellent help in times of trouble.
personally i wouldn't agree with the hope bashing above, yes initial black and gold versions would squeal, overheat etc but since the silver M4 and the tech m4 the pad compound has moved on a LOT is a lot longer lasting and powerful. easy to look after, easy to bleed.
we rode on out resin pads for 3-4 months then did an alps week and they lasted to all but the last day and we only changed then due to precaution we have since put the pads back in again.
oh and i had "the one" and avid 5, 7 and ultimates to compare them to, personally i liked the hope due to power (not as much as "the one") and ease of pad change and ease of maintenance. unlike the avid which are whores to change pads in and swap fluid and bleed!!
