Hi Rob,
Get plenty practice at a static roll cast with a shoot first then, when you make your upstream sweep keep the rod fairly flat and a good way out in front of you and bring the anchor further upstream than you normally would. When you sweep downstream, do it slowly with quite a high rod then "poke" the line out into the stream before setting up a static roll cast. Lay the D loop on the bank and let it sit for a second or two (as if it were a static roll) and the fly should come nowhere near the bank. It is not very dynamic but it will get a fly out when you are in a tight spot.
Cheers
Ben
Stay in the water :z3
Do they allow tubes on the Don?
If all else fails you could always use a spinning rod and a Rapala :grin, might need it if the weather is anything like the forecast.:shock :shock Away with your evil suggestions!!!...A worm is more like it ;)
