I dont know your style, but either of the 2 balls you mentioned are way to strong for the BR shot.
My 2 best pieces are the 505t and 715t and I will get a 716T, but way to much ball.
I ended up using a 300T that the guys(KYLE) at the Ebonite booth recommended and drilled for me
I would look at a medium symetric.
You should look at something even arcing and predictable backends, not snappy
300T
Gamechanger
Outburst
these are the ones I took
layout and surface will dictate what to use
there are other symetrics out there
Your house shot ball most likely will not work on this pattern
