[Which opticor riven would you keep]

Thank you very much Dreddeth and Zavenosk! I'll stick with the crit chance riven. 

[Which opticor riven would you keep]

Just rolled an opticor riven and these are my options:

1) 

+129.7 crit chance, +75.7% heat, + 102.2 crit damage

OR

2) +171% crit damage, +243.8% damage, -26.3% ammo maximum.

Which one would you keep? I had the crit chance one and I would hate to lose it, but an extra 70% crit damage, 245 raw damage seems super tasty. Thank you for your advice!
