Replying to STH 16 vs STH 16 steel?

Hey NS! i just bought some new JJs and i got STH 16 bindings on with them when i bought them, now im wondering if i should upgrade to the STH16 steel bindings or not.

First im wondering if its the same mounting point with both bindings? (im guessing it would be but id rather be sure about it)

also does the STH 16 steel differ so much from the normal STH ?

Just wondering mainly because i think a steel binding would prove to las longer in the long run but havent got any actual experience with the binding.

+K for help! no hate people!

Thanks.
