I use dektol and in my experiance it has performed the best. You need a strong developer to build up the contrast and I don't think D76 will achieve the best results, although it will work.
Different films will require different levels of solvent. I use a "hypo" solution that I add to the developer just as I use it, in a one-shot metheod. I documented what I did here... http://myfilmstuff.blogspot.ca/2011/...l-process.html .
