DOD is fun, but wear brown underwear.
Ive got my glow profile down a few times, usually over some nice long grass (I needed it once

)
Just take it easy and Practise, alot, then some more, and alot more, then you will get it.
Keep it up a bit for the practise then slowly bring it down. I find it easier in a bit of wind, keep the nose into it so it wont TR is much easier.
