What are the advantages to using two piece vs. four pieces?
I know someone to ask, but it'll be a week or so.
I think that he does this pattern in order to have a more solid feel on the sweet spot and to have a softer feel on the if he makes an off hit.
The tension I can't tell what it is because it's based on his preference.
If I was him I would put a lower tension on the poly(sweet spot) and put a tighter tension on the gut but I would not make more of a tension change of 2lbs.
Those are my thoughts.
Hope this helps answer your question.
