ColdDeath: Nice flip2upside down grind. But there was no real control to the grind. I know you can't "control" a car grind, but there was not a lot of balance and the grind was quite short.
Necros: Plain ole' boring grind, but the distance was excellent. Using two rails for the grind provided a lot of balance and made the grind very long, fluid and clean.
Since the challenge asked for a grind, I will cast my vote for the cleaner grind over the combo grind. Therefore, Necros gets my vote.
Its 2 - 1 in favo(u)r of Necros.
