bloke,
Started with pure corn...sweeter taste and has a definite appeal but its "limited" in terms of flavour. Next was 6mths of corn/Ryes...rougher stronger flavour well suites a single run to maximise flavours...can get bitey takes longer on ageing to 'turn" I reckon.
After some 5 years It's a more varied grain bill as it adds complexity, better balanced a nicer drink imho. Each to his own however and you might find something along the grain trail that really is personal fave. Impressed with the fact your prepared to experiment...it truly is the key to better enjoying your efforts.
here's current and very happy...
