in regards to your question just go mixed, it's not like you'll be ev training it for in-game and not like sceptile's bulk is anything special that it needs to preserve it. the higher attack will probably help when you end up having some mixed moves like dual chop/dragon claw later.
but don't evolve treecko until level 23 (iirc) because it'll learn giga drain, which grovyle and sceptile don't learn by level
