Riffles versus expanded metal for sluice-box?

I plan on classifying my material down to at least 1/4" so would expanded metal work as well as small riffles or should I use both? The area will also more than likely be heavy with black sands so I was thinking of running miners moss over some vortex to keep from loading up mat with black sand quickly. My understanding is that larger size material needs riffles where smaller classified material may not? I haven't done much sluicing in the past so please correct me if my thinking is not correct!

Thanks for the link Yankee Joe :thumbup:...rainy day here so this will be some good reading. Have a nice Memorial Day!
 
I classify down to 1/4" also and ran with the expanded over moss with success for our tiny flake stuff...... BUT then I bought a drop riffle sluice (angus mackirk) and highly doubt I'll ever go back to a Hungarian type system.........jmo for what little I do. Something to think about.............

What Angus Mackirk sluice do you recommend? I just bought the recon 2 but haven't had a chance to use it.
 
I have the AM Foreman. I "think" the Recon is that longer narrower one??? Anyways....I find the AM sluices are very forgiving as far as setting up and tolerate different flow(s) pretty good and cleanups are so fast compared to pulling riffles, expanded metal, and moss, etc.. out and washing...a real time saver! Combine what I just said with the fact that the drop riffles also do a great job of catching the fines it just makes the AM drop riffle sluices a win win imho.... I no longer sluice much but will never part with my AM sluice..... Get out there and play with your Recon...you'll love it!!!
