RGB pixel lights & voltage drop

Hi all, so I've got some pixel lights ( https://www.amazon.co.uk/Rextin®-WS2811-Digital-Addressable-Waterproof/dp/B01AU6UG70 ) but the 12 V version.

As these lights are quite close together what I intend to do is splice some new wire between them so I can space them out a bit, I'll probably want to add half a meter of wire between them so this is going to make the run quite long - about 25M in total.
I had a play around with them yesterday, I snipped the last LED in the string and re joined it at the end of 10M of that thin RGB wire just as a experiment. Well it did work fine with all the colours except white where it was flickering so I'm putting that down to voltage drop.

Ok, so I'm thinking with having a 25M run I'm going to have to inject some voltage at a couple of points along the run which is not a problem.

Questions :

1. would you recommend a thicker wire for use BETWEEN leds, if so how thick ?
2. what size wire for injecting voltage ?

Regarding question 1, the RGB wire is ( or seems ) the same thickness as the wire attached to the leds so would there be any advantage in having thicker wire between the leds ?

Thanks.
