IF money is no issue, buy TiNi. I buy plain steel because I intend to lube my case necks no matter which type of bushing I might use.
If the body of resizing dies are made of steel, and they resize the body and case web of cases just fine with the use of case lube, I'm utterly confident steel neck bushings are more than adquate on puny little lubed case necks.
