I was talking about the article, which is a weired mix of good information and "alternative truth", not the minis.
The metals of Pro Gloria, now Warlord Games are pretty good. While some details like pistols or glasses are more cool then historical, they are generally well made minis for the 1520-40 era.
The plastic set is, well, lacking in some aspects. My main concern is the lack of usable heads. 10 heads per 6 bodies, of which only three wear the typical barett, and that in an unusual wide style. Two of these are heavily feathered, which makes for repetitions in units. Of the other 6 heads there is perhaps one that can be used more then once, with the others showing unusual, atypical or unique heads. Imho this set needs four NORMAL heads per sprue more then it currently has.
In addition, the pikes have broad spearheads that look nothing like pikeheads and are a bit on the short side, and the three armoured bodies wear armour that is pauched or wedged, which was not used pre 1540 and only became common around 1560 – the rest of the style is 1520-40, though.
That said, the plastics mix perfectly with the Perry WoTR and Mercenary sets concerning arms and heads. With more heads usable for the ~1520 era these would be a pretty usefull set to create Landsknechts, Peasants, French or Italian infantry. Lacking these heads, they are fine for Fantasy.
BTW: Regarding that article. Just one fact that they got a bit wrong: Frundsberg did not die during the Sack of Rome. His withdrawal from the Imperial force due to a stroke (because the Emperor did not send money and he was unable to calm down his unruly Landsknechts) and the subsequent death of the Duke of Bourbon (who was in nominal charge of that army) lead to the Sacco di Roma, perpetrated as much by Spaniards and Italians as by Landsknechts. Frundsberg was at that time on his way home, and died later of this stroke.
