I use the husks because that is whatthe store had.
They seem fine. I don't find it hard to drink at all.
I have read that you have to use more husks 1 TBSP instead of 1 tsp because they are not as dense.
I only use a tsp though because a TBSP seems to stop me up.
Some stores might have it bulk in the bulk spice/herb dept. so you could get a bit of each and try them.
