I prefer this uniform anyway. Its a little heavier(well a lot heavier) material so it stands up better. Everytime I wear my 42s I end up having to get something fixed, and I have never had to reapair my 43s. Historically the 101 as a unit changed over before Market Garden(as well as almost all other paratrooper regiments), and the few paratroopers that didnt changed over immediatly after. So realisticaly the 43 were worn for more of the war.
