I recently switched from the 320 to the IG prestige pro. I used the 320 for about a year, nice racket. It had easy power but definitely had the feel of a modern racket, tinny almost hollow feel to it. Before switching to the 320 I used the midsize POG for many many years. Love the feel you get from those classic players sticks. When I switched from the POG to the 320 I was looking for something that had a little more pop to it especially when pulled out wide to the backhand side. I'm getting a little older and noticed with the POG that when pulled out wide to the backhand side alot of the time my shot would just float back short and be an easy put away for the opponent. With the 320 it seemed like when pulled wide on the backhand side the ball would land much deeper and I could stay in the point. A little more free power and little more forgiving than the POG. So I switched to the 320 and used them for about a year but ultimately missed the feel of a players stick. I demoed the IG PP and to me it has that classic solid feel of a players stick, while it is more demanding than the 320 it's easier to use than the POG in my opinion. The IG PP is easier to hit the spots with, honest string bed and have confidence to swing out. Where with the 320 it just seemed to fly on me sometimes. I think that might be to how open the string pattern of the 320 is, yes both frames are 16 by 19 but the IG PP is noticeably denser in the center/ sweet spot versus the 320.
Sorry to ramble.
