Unfortunately,I am not a fan of resin tracks due to casting quality and needing two types of glue to complete a model as well as sticking my fingers together. I like the Link`n` Length tracks in the Revell 1/72 and the Tamiya 1/48 tanks.
I have not got any RM tanks at the moment but looking at some pictures you only need to see the track detail around the drive and rear sprockets. Tamiya tracks are made up of two track links together with a slight curve so four parts fit around the drive sprocket so RM could do a few parts to upgrade a Sherman/Panzer IV without the need to make resin tracks.
The only real problem I have is what version of panzer IV i like best.....choices choices.....
