Good source for post hoc test selection?

Hi all - How do I select the most appropriate post hoc (post ANOVA) test? It's data from a normal distribution, 4 groups, experimental data from bending beams. My peers use Tukey HSD but I have also seen Fisher LSD, Sheffes and Bonferroni used. I have searched high and low for a logical train of thought to follow to select the right one but I can't find it, please help. :confused:
