I use a gentle roll cast to start, then a lift into the back cast. This releases (unsticks) the line with minimal water disturbance and additional line speed is possible into the back cast, with fewer false casts required. A roll casts at the start of the casting cycle also allows you to lift longer lengths of line off the water.
.... and be sure that only your tippet is drifting over your Trouts holding area not your fly line. Dress in muted colours, If you have to wade to get into position for a cast give it lots of time for things to calm down. Think about where you need to be for a proper presentation, plan it out.
