Iron Cross Trainer

Has anyone had any success using the iron cross trainer? More importantly has any had any success using this to train the maltese?

Also

I read one of Coach Sommer's posts saying the first book is at the printer. Does anyone know what the topic of it is? (or when it will be available?)

It's good trainer to same point, then you will need spotting and then alone.

I thnk it's not good for malteses, beacuse it moves your center of gravty to high and it's not the best thing. It'd better with pully for malteses.

I learned all of this stuff without of this, so it's not nessesery, but it's good pretraining to get aprox. 80% of strenght for cross, anoter 15% with spotting (deatails in strenght) and finaly 5% alone.
