The 31% probably isn't worth keeping. The 80% would probably be the best to power up because you'll use less candies and dust to have the same moveset and 2% isn't a huge IV difference. I would suggest possibly holding off for a few more 10km hatches now that Eevee has been moved to 5km, but if you'd rather just have one now the 80% is the way to go imo.
Snorlax dilemma
Hi everyone,
I really don't know what to do with my Snorlaxes.
I'm level 30 and I'd like to have a Snorlax to use in a gym but I'm very unlucky with egg hatching (I only hatched one over 461 eggs hatched) and I don't know which one power up. Can you please help me?
Snorlax list:
1) 2139 Cp, 31% IV, Zen Head - Hyper Beau
2) 1744 Cp, 80% IV, Zen Head - Body Slam
3) 965 Cp, 82% IV, Zen Head - Body Slam
Now I have 54 candies and usually I can find one Snorlax every 20 days.
Should I wait or can I start to power up one of them?
Thank you for your help, I don't know what to do... :)
Answers
Why would it not be worth keeping? He can still use it in it's current state, it's just that there's not much reason to power it up when his other snorlaxes would use the stardust / candy better.
If his pokemon storage is full there's no way a snorlax should get transferred over a pidgey / rattata / weedle etc.
Plus if trading ever gets implemented there are plenty of people who would take a 0 IV snorlax with the worst moveset because it's still a snorlax.
