You can avoid the chuck and duck and still fish deep enough by finding the balance between a fly's weight and your style of outfit, in my humble opinion. I prefer to tie flies with heavy hooks sparsely dressed, or weight the hooks with a few turns of lead or a tungsten bead. On a spey rod and long belly floating line many small to med sized nymphs and wets can be fished on a long leader without the adverse C&D effects. The flies, that are not too heavy but just heavy enough (#10 beadhead birdsnest, #6 purple peril hairwing on a heavy english salmon hook) to want to sink on their own, are cast just upstream enough to allow for enough of a sink to fish the depth you desire. If you need to get deeper tie em bigger and/or heavier and/or use a short belly with sink tip. You can then adapt the depth and fishing style (dead drift, swing) to meet the immediate situation.
The end of your flyline is as good an indicator as any bobber, and to approve or not of another's style of fishing is to apply your world view to another individuals world; one of the classic root causes of conflict in the history of civilization.
Life is but a walking shadow. A poor player who struts and frets his hour upon the stage and then is heard no more. It is a tale told by an idiot. Full of sound and fury!! Signifying nothing. May as well go fishing!
