There are a number of crop splines for TRS2004 made by DMDrake which I have used very successfully in TS2010. I downloaded them only last week from the DS 'black pages' to use in my Walled gardens - but to see them, the box for TRS2004 must be ticked.
Or not, I've done some testing and I haven't seen any such effect. Certainly not what I'd define as a "drastic" effect. But that is in TS12 - and if experience is any guide, Your Milage (not only) May Vary. It almost certainly WILL vary. (meaning this is the most inconsistently performing program I've EVERY used.)
