I'm good with the FIBA 3 point line, I've felt it was too short for several years.
I like the 20 second reset. Honestly after watching an 11 and 12 seconds run off the shot clock Saturday without a ten second backcourt count, I'd eliminate the 10 seconds to cross midcourt rule but that's apparently not on the table.
Wider lane is about 20 years overdue.
Quarters vs Half I don't see any real change there. There media timeouts sort of take care of the matter. I'd stay with halves simply because it has always been a game of halves but for a few years when the NCAA went to quarters and changed back.
