Combat models are not the best for scale and the are PIA's for putting together. It's not because of the vacuforming, it's just their poor design. I would suggest looking elsewhere for your 1/72 modeling quest. Yes, there are some 1/72 items out there. I would contact Lee at ScaleShipyard and ask him what is available. He has a good supply of hulls and hardware in your scale.
