I more and more rely on Aliphatic resin glues:
Specifically
*White Elmer's Glue All
*Yellow Elmer's Glue Wood Glue Max
*Titebond II
Sig Bond (yellow)
Sig Super Weld (white)
Deluxe Super Phatic (I like this thin CA like glue)

In my adhesives inventory also are:
White Gorilla glue
Testors Green and Brown
Duco
Sigment
New version Ambroid
E6000
Goop
DAP Weldwood contact
Elmer's Rubber glue
3M Super 77
Scotch 77
Various brands thickness CA's
Z-poxy Finishing resin
EZ Lam epoxy resin
5/15/30/90/min epoxies

Several questions:

But first some notes/observations:

Temp controlled shop
Build mostly Balsa and or foam and balsa 35 sized combat and stunt ships for sport flying only
Most aliphatic wood glues are over three years old
The white (dries clear) or yellow (dries yellow) do not seem to matter much with my covering finishing methods
All 4/8/16 oz glues stored in some sort of holder upside down
Some* of my glues are thickening inside the well capped bottle


I wonder if I need to pick just one...and buy a one gallon Jug and trash all these  4 to 16 Oz bottles...Then transfer to smaller bottles for use

How do I decide on ONE?   
Or should I?
Are the Sig products just re-bottled Commercial wood glues or do they have some unique quality?

Am I missing any real good glue I should try?

Max volume as I write this

I guess if I pondered my own usage the, ---should I buy a 1 gallon jug? ----is a self evident... no

I have not used up 1 16 Oz, and 2 4 Oz bottles in last 3 years..all about half full

I use the three different consistancies of BSI ca's, BSI epoxies, the original Gorilla glue, and Titebond III in my shop for both airplanes and custom guitars.  More variaties than that and I see no advantages.  I keep the ca's in the freezer until I need them for a project, then let them warm up for a day before starting the project, squeeze the Golrilla glue bottle to purge all the air and cap it, and do the same with the Titebond III.  I also buy smaller quantities because of the same issues noted by others here.
