Can anyone attest to how well a Tri-Cree can light up a thin neck? I test fitted a Tri-Cree optic in mine and it seems like because the dice are distributed around the star, a decent amount of the light will be just hitting the base of the thin neck, rather than going through. This is just from looking down the emitter at the optic, though.
Is the more centered Quad better suited for these sabers?
Colour illumination and brightness of a Tri Cree in a Thin Neck is very generous and more than acceptable. The actual perception of brilliance is still very subjective though. Whilst the close-set die positioning in a SF Quad Cree has merits, the wider-set die positioning of Tri Crees is not to be dismissed. The channelled focus of directional light will still be significantly dictated by several factors.*

and can offer a more scientific and detailed explanation with measurements and statistics (likely).
*In a nutshell from what I have followed over Topics here, general research and limited user experience dictating/influencing factors are: Focusing Lens, Thin Neck Light-promoting materials (like Mylar e.g.), Blades internal diffusing method, Blades external diffusing method either achieved by surface scoring of the Blades surface or elements with the Blades polycarb compound, Battery Size/Strength, mA measurement that's driven, Resistors.
Specific to Tri Crees vs. Quad Crees, (without elaboration on Cree-types used and presuming rates of drive, battery size and strength are relative) the Focusing Lens' angle of measurement and Lens quality will either heighten or lessen the resulting effect. Quad Crees whilst undeniably bright in a close-set formation, then become assisted with the Thin Necks Mylar Tunnel and then onto and downwards into a Blade. I personally find base flare is bigger but is dependant on Blade length as well and the required distance to maintain its strength over a changing length. I've got no problem with base flare.
Tri Crees, again driven down a Tunnel is still quite generous. Evenness (if you will) is marginally greater and base flare is lesser. Between the two though illuminated, whilst there are signs that can separate them I find it is not in-your-face obvious.
Between a Tri & Quad, rather than measure of brightness, I personally would look at measures of heat dispersion and retention. This much like Soundboards, some generate more heat than others and whilst long-term durability may be an allowance, it's whether the short term momentary lasting effects of the heat are acceptable to you with usage and if longevity is risked. With my (limited) experience, Quad Cree Thin Necks become much hotter in the Grenade and Switch Part than a Tri Cree.
As for which is better suited, umm.. 6 versus half a dozen. One won't be completely superior over the other.
