I'll agree that it is usually runs a choice item, but if you like the power of Eruption, try it with some choice specs... it commands seriously awesome power. While I would be hesitant to use an item like power herb due to the one time use nature of it, (you don't like choice, I don't like "all or nothing" items) I have tried lesser used Typhlosion (who is awesome no matter what) sets, such as Fire Blast, Sub Punch, filler - certainly gives surprise factor. I respect the out of the box thinking and I might have to try that ( what is your other coverage move? hp ice, rock, etc.?) I'm not sure how much time you have spent in RU, but the ability for Timid to outspeed Moltres and others is usually enough to warrant the +speed nature on non-scarf variants.
In reference to the earlier posts, there are good fighting types in RU, but they usually require more support than most teams can give. Generally Primeape with vital spirit and u-turn is an excellent scouter, hitmonlee/chan are decent spinners, Hariyama is not seen as much now, but is still a bulky hard hitting guts abuser, Poliwrath boasts excellent resistances and can also fill the roll of bulky fighting type, and I know there are others.
Gallade is an effective lead, but patience can be a virtue. I usually carry a CM chesto-rest Cofagrigus which beats the Standard Sub Bulk up Gallade; however, if he is worn down from spin blocking or has already used his chesto berry - which often has happened later in the match, Gallade can beat him and pull off the sweep.
