No. 1 - Light and Clean - Maltiness is subdued, color is light, citrusy hop flavor takes spotlight.
No. 2 - Malty/Fruity - bigger malt presence, fruity/floral hop flavor and aroma.
No. 3 - Spicy - rye and darker caramel malts dominate. Amber in color. Big hop profile.
No. 4 - Black - An IPA posing as a stout.
The following is a batch of No. 1 that I brewed today. Still probably needing to tweak a few things in future batches, but this may be a winner...

85% 2-row pale
2% crystal 40 lovibond
7% corn sugar (added to boil)
Hop Bill (IBUs = 95)
Zeus (16.4 aa%) and Chinook (13.0 aa%) at start
Chinook 15 minutes in
Zeus 30 minutes in
Amarillo (8.5 aa%) and Chinook at finish
Amarillo dry hop for 2 weeks
1 oz gypsum added to 12.5 gallons of brewing liquor. Final volume = 7.5 gallons.
