Chaff recommendations?

I use Badminton Easy Rider Chaff - no barley, no alfalfa, no mollasses, - low in sugar mine eats it all up and she fussy. Its about £7 a bag.
Mine has to have no sugar low starch and no alfalfa as turns into a nervous wreck on alfalfa.
 
For what its worth the only chaff (un molassed/low in sugar) that my diva mare has not rejected outright, is Top Chop Lite. Its very finely chopped and smells really good.
