I don't do my own hybrid workflow for E-6 stuff. Essentially, when I get slides back, I look at them on the light box, project 35mm, sometimes load MF in my enlarger and point it at the wall. When it comes time to printing, I don't want to have to mail off slides for scanning, then get scans back for editing, just to then upload or send files for printing. I strive to get the right color balance on the slide, so all I have to do is mail out slides for printing, with the note "No corrections. Print to slide."
I've had great luck from this process. I've tried playing with color balance in my enlarger, and specifying color correction units when mailing slides, but it's not a replacement for getting it right right off the bat with filter selection, and prints will come back not quite exactly how I like them. Same thing with exposure... I strive to be dead on, and find it's easier and more economic to bracket if it's tricky than to have to send off for scans to correct myself.
I wish there were economic options for 35mm slides, as inviting everyone over for beer, pizza, and a slideshow after a nice canyoneering/climbing/backpacking trip is always a blast... Can't have whacky color balance for that!
Also, being that careful with C-41 (and B&W, too!) is very helpful. Scanning yourself, and I imagine RA4, are MUCH easier if the color balance and density are the same shot to shot.
