Its a pet peeve of mine when people think certain techniques are "trendy" when infact they are just forgotten or not well known. I am sure a lot of people thought Rob Leatham's pistol grip was trendy, along with wonder nines, $50 slings, and weaponlights that we now take for granted. I remember seeing pictures somewhere on the internet of MUSKETS with single point slings.
