Which Snorlax to evolve?
1.- Lick + HyperBeam 91.1% IV 12/14/12
2.- Zen HeadButt + HyperBeam 86.6% IV 13/13/13
3.- Zen HeadButt + Body Slam 86.6% IV 14/14/11
Answers
Either Lick/Hyper Beam or ZH/Body Slam
Lick Hyperbeam is really fun on attack, it's hilarious to see snorlax being so athletic and jumping 3 times a second attacking
ZH/BS is obviously his best defensive moveset so if you want to use him as a defender (which is better than him as an attacker) then go ahead.
i'd power ZH/BS first then lick/HB.
That ZH/BS will probably sit higher than either of the other two, thanks to its high attack ivs.
For example, a 15/13/13 (91%) will max out 10 cp higher than a 13/15/15 (96%). With the upcoming gym rework though, cp may no longer be relevant.
ZH/BS is also the 'best' defensive moveset on snorlax in my opinion, and I am sure others with this moveset share a similar view! BS hits hard and often and gives no warning more often than not.
