For a bracket car I’m not sure I would chase the last bit of ET by going roller unless you really need to. They both can fail, but the feeling I have is a SFT failure is most likely an attention to detail thing. While a SR seems always to have a life span that starts from day 1 and goes to............ouch! Yesterday! That being said certain classes put you in such a box a roller is the ticket. I’m sure one is in my future. Just have to get appropriations to agree! :)
