M - CV - Just never grows old. Always fun and extraverted, zest of life.
F - BBB - Just so you can say you did, and how you never would make that mistake again.
K - TZ - No flow, half the PF occluded, always just a total buzzkill.
But in all seriousness, for any given machine there are people in all three categories --which makes this hobby f**kin awesome.
