Cwing KE4 Max is probably the most Ping G-like although probably not as large looking. Kind of a bargain at $30 these days.
The TS1-IM is in between the TM P770 and P790 IMO. Love the look and feel of this one
The TS3 is maybe more like a Srixon or Cally forged cavity back? Also a favorite with very soft feel.
If they still have the TS2 that's a mid-large size forgiving cavity back iron.
I haven't tried all the Maltby stuff, but all of the above are very good.
