Should I keep Pokemon with high CP, Attack, or Weight?

Forgive me if my Google skills are poor but putting so many words in a question didn't yield a satisfactory answer to me on the web.

I caught multiple of the same Pokemon. I want to transfer them to get candy and free up space to catch more. However, which one should I get rid of, high weight, high CP, or high attack?

These are the rough numbers from what I remember before I transferred them but hopefully they illustrate my question/dilemma. The numbers aren't exact since I had already transferred them since I needed the space but is basically what I observed.

Pokemon A

CP: 294 
HP: 52 
Weight: 30.53 kg
Bug Bite (bug) 6 
Poison Fang (poison) 15

Pokemon B

CP 280
HP = 54
Weight 31.0
Bug bite (bug) 6
Signal Beam (bug) 35

Pokemon C

CP 190
HP = 46
Weight 27.9
Bug bite (bug) 6
Poison Fang (poison) 35

Poke A has the highest CP out of the three. However, its attack is the weakest of the three BUT it has two different attack types (bug and poison).

Poke B is almost the same as A but it's a little heavier, the HI is slightly higher and CP is slightly lower but the attacks are higher than A, but it's only of one type (bug).

Poke C has the lowest CP, HP, and weight but just like sports, since it is behind by 100CP, it's POSSIBLE thru training and stuff that it could get up to its big brother. Also, in addition to growth potential, it has both types of attacks and both attacks are high.

So which of the three do I keep? Poke A b/c it has the highest CP, Poke B b/c it's close to Poke A and has better attacks and slightly better HP, or Poke C due to its potential and attack?

Always CP if it is not the final evolution, otherwise abilities unless the CP gap is significant and you don't want to spend stardust to power it up.

It's currently unclear what, if any, influence the weight and size of a Pokemon has on its stats, so I would ignore that for now. If you are going to evolve the Pokemon then its abilities will change, so ignore those if it is not the final evolution. That means that when choosing which Pokemon to keep for evolving, you should only consider their CP.

It is a little more complicated on the final evolution, but it mostly depends on how much stardust and candy you want to spend on powering up. If you want a decent Pokemon to fight with but don't want to spend a lot of stardust and candy to power it up, then keep the highest CP. If you want the absolute best Pokemon, then keep the ones with the best abilities. You can always raise the CP by using stardust and candy, but you can never give a Pokemon better abilities.

Also keep in mind that as you level up, you will naturally run into Pokemon with higher CP, so there is little point in powering up something common like a Pidgy. It may be worth it if you get something rare though, especially if it has really good abilities. It'll depend on how much stardust you have, how long you think you will fight with it, etc.
