Long frontside noseslides are rad, short ones are dumb.
Blunts on ledges are rad, blunts on rails are dumb
Noseblunts are ok on rails, better on ledges. When somebody comes from behind a waxed-to-death ledge and falls out fakie though...eh...not very cool (also, the only way I've ever done a frontside noseblunt on a ledge)
Re: the front lip debate: its all about how slidey the surface of the ledge is. Recycled plastic or overwaxed- not that cool, unwaxed or barely waxed, making that screech noise as the wheels resist the slide you are forcing them to do- pretty cool. However, regardless of the coefficient of friction of the ledge, boardslides on ledges where the wheels slide never ever ever will be cool.
Nollieing into slides makes their coolness factor invert- a lipslide is cooler than a boardslide when you ollie in, but when you nollie in, its the opposite. A tailslide is cooler than a noseslide, but when you nollie in, its the opposite, blunt/noseblunt works the same way. I almost want to say same thing goes with smiths and willies, but even nollieing into a willie can't save it.
