I understand your frustration - after stripping there is no line to cast and you waste huge time with your fly out of the water getting a belly to cast, as discussed in some of the previous comments.
Perhaps there is a tip or two I can impart - when these work I think I'm a genius - when they don't I'm still the same old Idiot of course.
From the beach or a point, fish the seams caused by tidal flow (incoming is good) just as you would fish the softer water just inside the seam on a river - cast bait fish patterns across the rip, shooting some running line, and swing it across into the slower current, timing your depth. They seem to prefer the slower current speed side while still swimming up current. Seams will move up and down the beach as the tide evolves.
I think that schools of more than one silver (as observed from a boat) will follow the fly and loose interest unless stripped hard. Hence the technique of a hard, BIG two or three - three foot strips, let SINK, (count seconds to judge depth), then STRIP!, STRIP!, STRIP!- LET SINK - STRIP-UGH!! - HOOKUP! WHA HOO!!.
When you have stripped in your running line and the belly is at the tip or at your casting spot, snake roll and shoot running across the seam, mend, move down the seam, swing, etc, etc
