I own 2 sets of the new Nitto/Riv Bullmoose, and with the extra sweep and
width I think the new ones are the bee's knees.
BUT.. I do also have a few sets of the older type, and while (as Jeremy
said) they do vary in shape, width, sweep and rise, I think alot depends on
the bike as to how well
I've only used the new ones - which I like a lot, but I need to cut a
little off the ends for my short arms - but the only major difference I see
is that the originals had a straight section instead of the continuous
arcing curve of the Rivs. I doubt there's much difference in grip position.
There were many variations on the bullmoose theme that came on early MTB's.
Some had much more vertical rise than reach, others were flatter. Some
were cheap, heavy, chromed steel, others were nice chromoly. Of the ones
i've seen, the 80's ones were generally much straighter--with less sweep
