It seems, with these trinkets, that the on-use ones are rather weak. The Strength one only gives 1277/1441 Strength, while my 359 trinket from Tol Barad gives 1605. That is nearly a 200 Strength drop going from a 359 to a 391. If the stats stay the same, I'll take the one that gives haste and stick with my 359 for on-use strength.
