dampair,

casting flies can be very effective for silvers either from a boat or from the shore. my experience is casting flies in the neah bay area from a boat... and fishing can be incredibly good at times (god, the ocean was great this year for silvers). sinking lines are the most used lines. i prefer a shooting head system, and when i need to dredge up some silvers i fish a 25-30' lead core shooting head... but slower sinking lines can be very effective early in the morning or during the cloudy and/or foggy days. bring a floating line along for when you see silvers feeding on the surface and throw small sliders and strip them across the surface (you won't catch as many fish on top, but it's gotta be the funnest way to catch them). for subsurface work, flies such as deceivers and clouser minnows are great... my favorite is a chartreuse and white flashtail clouser.

hope that helps, you don't need to go to bc to catch silvers on a cast fly.
