Like a Monkey Grip? Never really trusted that type over four bolts TBH..
nah, it kind of slots in, and
has four bolts, clamps at the rear though, but with a nice rounded design, its a very well designed bit of kit.
Im not a massive fan of that Hope one personally, I quite liked the older version, this one looks a little steroidal, like it was done by someone with a 15 coffee's a day habit on a CNC machine <adopts the voice of Animal from Police Academy 2> "jjjust give it mooore like, um, ha ha, er, like big machiney bits, and aaagh, you know, um, like, machine it"
still, bet its light and stiff
