PFS: Unchained summoner compromise?

[derpdidruid]

In a recent PBP recruitment thread someone told me that, if you want to you can use the standard summoner with the unchained spell list. Since I can't find this rule anywhere (why google foo!) I decided to ask you guys if this is correct.

For PFS? No. You need to use the Unchained Summoner in its entirety for any new Summoners.

You can't, you need to use the UC Summoner. Besides, your threads are in the wrong forum.

Well drat. I hate what they did to the eidolon in unchained. Guess I have to suck it up though.

If it's a PBP the GM can allow it, if it's to use PFS-rules, then you can only use the Unchained Summoner.
