you know me gaston, im a fuckin fanatic at this point i preach halo like scripture, lol. the vibration is something that is minimal at most and something you don't even notice after continued use. like i said i had reservations about using with the derlin even maybe wouldn't kill the vib. enough, but like before underestimated the halo and its abilities, i love the derlin rpg with it now, and am saving for some of the aluminums now. all hail the halo, can i get an amen?!
