@ Adehl: sure, see below, though I don't think this will add much to the conversation: the curves still look the same, just higher up on the graph. As can be seen from the graph, for the the 541 trinkets: renataki's > Bad juju > Talisman for all fight durations.
Regarding your other question, the only trinket which affects the value of other trinkets is the Talisman, as it procs haste, which in turn increases the proc chance of RPPM trinkets. Our current trinket list
here (this is a link) lists the value of trinkets used both with and without a talisman - as you can see, the effects are very small.

@ people asking which trinket to use:
this list (this is a link) has all the trinkets, from un-upgraded bottle and relic to heroic thunderforged ToT trinkets. Additionally, as pointed above, we also have shadowcraft, which has been updated and is now modelling trinkets fairly accurately (except for RoRo, which no modelling tool is simulating accurately for the reasons given elsewhere on this thread - and I understand simulation tools aren't either).
