Shave and Haircut - Part 1 (Scale)

I am deep in the throws of a project requiring Shave and Haircut for Maya. I have been using this software on and off for the past year or so. Slowly and progressively learning how to manage time and get good results. I have posted many questions on the forums hoping to get a response, but there don't seem to be too many folks forging the threads for shave and haircut topics.

Anyway the first thing that I want to talk about is:

Geo Scale:
First things first, the scale of your object and the scale of your hair is very important. If the scale of your object changes, (for example your animal gets referenced into a scene and the animator scales him up) this will mess up how you originally intended the hair to look. So make sure your model's scale is fixed and that in no way in the future will his scale change before starting to work with Shave.

Hair Scale:
By scaling up and down or using mattes to scale your hair, this can affect the integrity of your clumping down the road. I have found that it is best to create your hair, and then use the scale brush tool (make the brush big, zoom out and scale all the hair down to the approximate length). I hear this is much better than attenuate because attenuation can cut your hairs too short and you'll be popping and fixing hairs rather than having control right off the bat (A great tip by Chris Chrisman). From there, I will minimally affect the hair using black and white maps until I have it right, or I will cut the hair, (this is an assumption but this seems to reinitialize the hair's scale to a default setting rather than globally affecting all of it attributes).
