It's worth considering overload exercises instead of assistance exercises.
Bench lockouts off the pins.
Becasue of the limited ROM you can really push the weights up.
for me the numbers look like this ...
Bench LOs @ 120 % Bench 1rm
Squat LOs @ 200+ % Squat 1 rm
Rack walkouts @ 180% Squat 1 rm
Rack Pulls @ 150% DL 1rm
That has got to be better than curls and lateral raises for increasing strength ye
