I did use the clipping path (pen) approach for a long time and it has certain advantages for sure. The main problem is that it only allows a uniform feather around an edge, which can have limitations. (The following method can be used to generate a clipping path from a selection if one is needed)
What I have found is the fastest is to use quick mask to rapidly paint out the main areas. Using a pressure sensitive tablet (of course this is essential) then using the '[' and ]' keys to rapidly change brush size as you work around the outline. Once this is done, (using a 50% flow on the brush and allowing some build up), switch back to selection and make a clipping mask.
You can then use the technique described by Martin Evening to fine tune the edge. (Gaussian blur on the mask then use the levels adjustment on the resulting blurred mask to fine-tune where the edge appears).
If you did manage to shoot against a suitable even backdrop you could magic-wand select the background, then hit quickmask and use the method described above to fine tune the parts of the edge where the selection has become incorrect.
Overall I find that although the above method sounds time consuming it can become quite quick with practice. There is also to me something more satisfying about painting the selection on rather than clicking on points, I suppose its a throwback to those middle pages in the Rupert annuals where you would just paint on water to see the colours appear :-)

Except if the bg color is stronger than the subject's it'll bleed into the shadows, and if they're running type round the pix they'll probably need clipping paths (i.e. the pen tool)
We shoot thousands of pix like this, and we've never found as good a substitute.
