Upgrades for KWA/KSC G23F

[Varsa]

Hey!
I have a unmodified KWA G23F that part. 24 the floating valve broke on. Im planning on a full modified Glock but dont know what upgrades to buy. Due to my thin vallet I'm going to wait with the inner barrel, metalslide and recoil spring guide.

Upgrades:
$22.50 - KM 6.04 TN inner barrel KSC G19
$55.00 - KSC Metalslide
$10.00 - Zenith Recoil Spring Guide For KSC G19 Series

$11.00 - Firefly Rocket Valve for KSC G17 / G18C / G34 ( Part No. 24 )
$06.00 - Hidakaya Plug Spring for KSC G17 / G18C / G34 ( Part No. 25 )
$09.00 - Hidakaya Hammer Spring for KSC G17 / G34 ( Power Up 150 )

I have already modified the stock magasine valve to hi-flow.
Also a few ball bearing balls in the gas chamber in the magasine to help gasification.


What upgrades from the other guns do/doesn't fit the G23F?
Do you think I should by some other item, like Shooters Design or Guarder, instead of the Firefly, Hidakaya or Zenith?
What kind of inner barrel are you suggesting?

All help and comments appreciated.
