Re: max block or max life
Full Tal's + Magefists + Perfect FCR 'Spirit' = 8-frames casting breakpoint, with rings, boots, and charms still able to be customized... it's just a natural 'fit' for a Meteorb, and Spirit does have some very nice mods.
Since "Speed is Everything" in MF runs, your other options (9-frames casting with max-block, or going with a partial-Tal's) aren't as appealing to me.
@Soulburner, remove one piece of the set.
otherwise, no
