How to *Really* Use full bow hair?

[tchaikovsgay]

Guys I need to know how to use full bow hair as I need to play a slow Sautillé passage (the more bow hair->the slower the bow bounces) and I want to produce a fuller sound...

Some say 'to use full bow hair, tilt the bow stick away from you, just slightly'

I don't get it?? my strings are absolutely parallel to the ground, isn't most bow hair is used when the bow is not tilted either towards or away from me at all???? 

thx

There is a comment below saying that when the violin/ neck is parallel to the floor, the strings have a bit more of an angle so what you think of as vertical to the violin is not vertical to the strings. Now, if, as you say, the string are parallel to the ground then do as you did before. A little tilt, no tilt, whatever, why not try out what angle bounces the most and most easily?

Yes, I think I need to do some experiment on Sautillé, but I get why ppl say 'to use full bow hair, tilt the bow stick away from you, just slightly' now!! thx

Tilt of the bow will let you make small but noticeable changes in the sautille. Think of it as something to add variety to the sound. 

The physics of the tilt is to use fewer hairs on the string, essentially changing the spring rate of the bow hair system and thus the bounce effect.
