I'm not talking about difference in rules, I'm talking differences in character, or how rules might affect play.

Home advantage generally isn't as strong? NRL teams don't have to travel like S12 teams, and climates don't vary as much.

Season is obviously much longer. Futures would be harder to profit off.

How much harder is it to beat NRL or super league?

I'm looking at adapting my S12 system to league (nrl and super league), as it'd give me alot more matches to look at, but little more effort required.

I assume aussie books/british books are much sharper on NRL/Super League than union. What sort of betting limits are there? Does anyone here use offshore books (I mainly use offshore and prefer them, but are they competitive on league?).

I know there are alot more statistics available for the NRL than for S12 (which might be good or bad, depending on how you cap).
