[PFS] Optimized Occultist Arcanist, Advice?

[Fearspect]

Here is the build that I think I have settled on for my Pathfinder Society character, would love to hear your thoughts on how it can be improved:

-Main Role: Battlefield Control
-Secondary Roles: Shut down spellcasters (at high level), Utility Summons, Quick access to utility spells

Tiefling Occultist Arcanist
Traits:
-Reactionary (+2 Init)
-Student of Philosophy (Use Int for Diplomacy to convince, Bluff to lie)
-Prehensile Tail (Retrieve object on person as a swift action)
-Vestigial Wings (+4 Fly Skill)

Feats:
1) Extra Exploit -> Bloodline Development(Arcane) -> Arcane Bonded Ring
3) Spell Focus: Conjuration
5) Augment Summons (+4 Str/Con on sumoned creatures)
7) Persistent Spell (Metamagic)
9) Evolved Summons (Add 1 Eidolon evolution to one monster you summon)
11) Extra Preparation (Prepare 1 extra level 5 spell)

Exploits:
1) (Taken by Archetype): As a standard action, pay 1 reservoir to cast summon monster I. Every two levels, increase the summon and pay 1 more reservoir (similar to Summoner). Summons last 1 min/level. Cannot have more than one of these casts in play at a time.
3) Dimensional Slide (Pay 1 Reservoir to reappear a distance away)
5) Quick Study (Pay 1 Reservoir to prepare a new spell in the place of an existing preparation)
7) (Taken by Archetype): Gain Augury and Contact Other Plane uses
9) Counterspell: Give up a spell cast one level higher and spend 1 reservoir point to counter a spell as if using dispel magic
11) Greater Counterspell: Can now use same level spell slot to counter

Starting Stats (Includes racial modifiers):
Str: 7
Dex: 16
Con: 14
Int: 18 (Level 4 & 8 stat increases go here)
