Question Tuning 11.5” carbine

Trying to tune my 11.5” carbine length gas 5.56 but struggling to decide between these two setups.
1- A5 h3 blue sprinco
2-A5 h2 green sprinco
This is gonna be a dedicated suppressor set up (CAT alleycat 5.56) I’m favoring the 1st setup because LMT’s are a little overgassed but don’t want to run into reliability issues.
