Heya Folks!
I have to use fume for an avalanche shot in a commercial so I've been playing with a lot of things in the past while. You seem to get a few different types of avalanches, those with loads of rocks of ice being flung around which are followed by huge amounts of powdery snow and those which are sheets of ice that detach from a mountain and slide down along a mount with a huge plume behind them. It almost looks like fluid along its edge so it's like a continuous white surface. I've tried a few different approaches including realflow, glu and particles to get this and while I've gotten decent results it's nothing conclusive. I was using particles bouncing or sliding down a mountain leaving afterburn trails which worked quite well but I have to get right up close to the leading edge of the avalanche. Since afterburn is birthed via particles and not continuously, it kind of breaks a bit and the effect doesn't build up into a cohesive mass - it does look like isolated puffs of smoke instead of something like this:

What I'm wondering is how to get things that look like this and look good and crisp up close.These videos are a good reference:

Any of the fume stuff I've done has always been roughly man size so I haven't done anything on this scale at all - I'd prefer to use fume or particles with fume from a controlability point of view but still get a good continuous leading edge.
Has anyone done anything along these lines or scale? I'm going over the manuals again and running a good few tests but any pointers would be very much appreciated!
P.s. here's the rubbish ab test - Supposed to be at night time hence the dodgy lighting
