Cases like 2345578TTTKKA also require that you split the wheel in order to make a full house in back w/ pair in front. I wondered what the dividing line was--- how bad of a low was it worth keeping?

55TTT 23478 KKA is a no-brainer
55TTT 23479 KKA is also worth it, but
TTTKK 23457 5JA is better than 55TTT 2347J KKA, and
JJJKK 23457 5TA is better than 55JJJ 2347T KKA.

I thought this was one of the more interesting hands in my list:

2h4h7h9hJh 3d4s5cTdQc 5dAhAs

Here the low is quite bad but there is really no other front/back alternative which is nearly anywhere as strong.

I think switching 23457->23467 to use the five elsewhere is almost always correct, you are sacrificing only about 5% of middle strength.
