the Trifecta requires oil, and a medium condition is not enough oil for it. Compared to my Paradigm on medium, the Trifecta burns up early and hits very soft. It covers 2-3 less boards than the paradigm. The Paradigm crushes the pins. On medium heavy, the Trifecta hits very hard, harder than the Paradigm, and covers 1-2 boards more. On heavy oil, the Paradigm barely moves, the Trifecta acts like someone is kicking it towards the pocket. Very strong defined move to the pocket, and hits with a lot of force. It's really finds itself on those conditions.
I just added a Passion last night, and put 7 games on it on a heavy condition with solid results (it and the trifecta can be used interchangeably, but I have 2 different approaches to the pocket it one isn't carrying). I'm going to throw a practice game on a medium condition tonight, and I'll let you know the results if you want.
