I share the same feeling fly_boyz.
On high hovers with some amount of wind, I am almost sure to get one when making a 360 (as I stated before on a R44-II, did not experience that on the R44-I). So I tend to agree with some kind of TR/MR or other interference (slow translation unawareness) that catalyses VRS.
I cannot comment on your recovery, because I always had hight and got out of it according to the books (using more than 150 ft...).
My statistics are so bad that I would not do a high 360 without a positive vario of at least 200 ft/min
