I personally have switched from a push to a snake.  I think that my push was pretty versiatile.  I can shoot it long, stright, cut back, middle.  It worked for quite a while and still does occasionally.  But if I try to shoot it for a whole tourny I get fatigued. Squaring it off gets hard to do.  Oh, and a side note,  Rios is just pissed cause he can't shoot a push!
