Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
Jason,
Just to continue Graham Korn's suggestion of Tumbling Dice, I have their Viking packs on the way to me now and I'll let you know what I think about them compared to Strelets Vikings.
307. CHAINMAIL CROSSBOWMEN is the set you want I think
Oh and how about the Valdemar set: Mercenary Crossbowmen?
Check out Thunderbolt Mountain's 25 mm Arthurian range. Though somewhat taller than most 1/72 plastic sets, they are much truer to human proportions than most metal sculpts. Unfortunately the crossbowman they offer is probably over-armored (chainmail, helm and quilted gambeson) for the Crusades.
