I used a tame deino with a 96 asc saddle and 36k health . The only real hassle is the wait time between feeds . I fed a 150 once and then just kept swimming in circles till the food meter went down , usually takes about 500 less food Loss to be ready for next feed . Try to wipe out the area around , it’s a hassle when a random tuso can grab you and it’s stuck in the wall.
