I asked a hanging buddy of mine about this and he said that in fact, you want that 20-30degree twist, because that is what gives the hammock the greater comfort and larger "sweet spot". He took a piece of paper and twisted it slightly as the MSBs would twist the hammock and said "See, the diagonal is almost completely flat."

He suggested putting the RL at the upper end of the twist and compared it with a weight distribution hitch.

Just saying....
