Question for speedpainters 2.0 and brushes from the army painter!

Hello Painters!

Quick question about people who paint with Speedpaint 2.0 or any contrast type of paint using army painter brushes

My question is about: from the line of brushes from the army painter is the best/right ones to use for speedpaint minis?

I want to keep the focus solely on the army painter brushes

I know the army painter have 3 SKUS of brushes: the red circular handle ones, the white triangular (wargamer) and the masterclass (the black handle ones)

My question is, which is the right one for speedpaint minis? does it matter? I really like the wargamer ones (the white triangular handles) but not sure if they are made for speedpaint

Another question: does the length of the tip matter? is there any specific size for speedpaint vs acrylic? what about circular vs pointy tip for speedpaint? painting with speedpaints I need to focus on getting circular tip or pointy?

Tell me... you use army painter brushes for speedpaint minis? which one you use for basecoating from what line of sku?

or doesnt matter at all?.... get the ones that I like with the size that I need from, any of those brushes will be good for speedpaint

Thanks in advance for your guidance!
