I have come to like outside Iso very much as i have a PF trainee with real good outside shooting. He performs real well in that offense.... .
I am thinking of putting my SG in PF position as you mentioned that your PF performed well because of good outside shooting. Let's see whether it works or not.
BTW, what is the difference between inside isolation and outside isolation?
I used both strategies, but both mainly relied on mid-range shots.
