Vertical TMR. Whole bales vs grinding hay??

So guys lets talk about this. I just purchased a jaylor vertical mixer wagon and I'm wondering for you guys that have vertical wagons do you run all round bales in your wagon or just ground hay or both or what? I've hear people say that they run bales through all the time an have no Trouble some others say that it wears on your mixer a lot. Tell me what your opinion is on this topic. For all brands of vertical tmr's jaylor especially. Thanks guys
