If you get accustomed to convergence issue you can try my favorite PeaksBaby, designed especially for Alpine:
DHS
ENDO
XL 385 (from my 9M)
2 ERPPC
LRM15
2x LRM5
Tag
Target Decay and Advanced Sensor
Have at least 1.23 Heat efficiency (you balance the ammo and DHS to your convenience ) that way can chain fire the ERPPC without overheating
Full armor swapped some rear to the front to lessen the side torso risk.
85pkh with speedtweak.
I noticed that i do few damage with the LRM, but due to the hard point that's the only way to be annoying from long range. I would have loved a 4 ERPP setting
One tips for shutdown mech: over 180 meter to 350 meter... dont bother locking, if the mech is tanding still or shutdown just fire the full volley he will take it all
dont forget you dont pack that much armor..and usually you'l die mostly by your side torso with pristine armor on the arms, so time to get more skill and learn to torso twist and aim faster (that's why i chose ERPPC over LLas or ERLLas) You shoot, you twist.
