I missed your question Brett but Best Bet has done very well for me. (don't worry about the pics, with as few irises as I currently grow yours are a fine addition!)
I recall buying a pair in 6" pots and they were quick to multiply and bloom. They quickly outgrew they're allotted spaces as my daylilies multiplied and were replaced with smaller daylilies. I gifted several divisions and the rest ended up at Mom's place, I see no problem in snagging myself another nice chunk or two.
These are the only iris I have that has actually re-bloomed for me, I believe that was year 3 in October no less. I'll give mine a little extra attention as Fall comes on, hopefully have so re-bloom to post!
Edit: mine had to have been purchased in larger pots, 1 gallon? I had blooms the first Spring after planting (roughly a year). They've definitely been quick to multiply as well.
