i have been running the mt-m hp7 for about a year. they are very very strong, and do not bend in wrecks
i regularly bent the renthal fatbars.. and they do not make cockpit feel cramped...i am a stand up rider.. i can't compare them to anything else, as i've forgotten what other bars feel like at this point... i know that i'd definitely buy them again - as i said, they are very tough.
they are oversized. - 28mm - 1 1/8" at clamp.
if you like the bars to be in your lap, and are a sit down rider, these will not work for that.. they have almost no sweep, and are very straight at the ends - very trials like. but much stronger..
