Thinking about the 'doubles' thing...
Trodax is right, Str, PA and such additions should not double, they should just be added once the damage dice have 'settled'.
I was thinking that Sneak Attack and its cousin Master Fencer (and other damage dice adding feats) should possibly work thus:
Say you wield a 2d6 weapon and have sneak attack of +3d6.
Roll all 5 dice and count only the two highest or doubles/trebles/quadruples/quintiples. In the latter case count only the sum of two of the dice toward the running total but re-roll all the matching dice and proceed until none of the dice match.
Thus if I roll 1, 3, 3, 3, 6. I take the matching dice (3s) and count 3+3 toward the running total of damage. I then reroll the matching dice and score say 3, 5, 6. No dice match so I pick the two highest - 5+6 and add 11 to my previous 6.
I've scored 17+str+any other bonuses in damage.
Improved Crit can add an extra dice perhaps, being treated in the same manner.
That may be what Clovenhoof was advocating before, in which case I will sacrifice myself to the demon of his choice.
