Juicemotoparts now recommends that only a bushing is used on the titanium wrist pin, I have one that just failed big time after only about 50 miles but I was running their experimental aluminum bushing, and I hav seen pics of other titanium wrist pin failures when someone ran a needle bearing on it, I know that at least one of them that failed was running a used needle bearing that haf been run on a steel pin previously which could have been an issue, but I think a bronze bushing on the titanium pin will probably be ok, nothing to gain by using a titanium pin and bronze bushing over a needle bearing and steel pin in the weight department because the titanium pin and bushing actually weighs 2 grams more than a steel pin and bearing.
I wont buy another titanium pin I dont think, and im not sure if I'll ever use the two bronze bushings I have or not but I may try one at some point.
Whatever anyone does I highly recommend staying away from the aluminum bushing.... not a good Idea, emailed juice with my results so maybe they will pull that part from their web site before anyone else trashes a piston, wristpin and possibly the jug.
