Tim, another Tim here. Parrott'ing what everyone else said, your OS should know!
I was hell bent on going ceramic for the longest time. not a bad choice, but learned along the way that my size MAY limit it's effectiveness. A tad smaller than you, am I (6'1", 225).
I chose, with the expertise of my doctors, a large ball Metal on Metal (Titanium). The larger ball makes it less prone to dislocation, & range of motion is sometimes increased. Still being very active, that's what I wanted.
Research THR's on the internet, and ask lots of questions to your doctors. Also, dont be afraid to ask for second opinions. This is a huge deal, and you need to be 100% comfortable with what product & procedure is best for you.
Good luck Tim! I get mine on September 28th. Super stoked!
