Sag always grows short for me. The light on the tank is the Fluval 13w light anyways. I thought about vals but they grow so tall. I'm either going with the banana plant + anubias in the front, or an all anubias tank.
im a fan of brazilian pennywort. the plant grows like a weed and if planted grows straight to the surface. the leaves are situated around the stem. if you grow it floating, then the leaves will stick on the side closest to the surface. i have not grown it emersed yet though.
