On arena hangs I still see folks eyeball leg angles; I’m consolidating a pocket guide and an Excel that outputs leg tension, checks 8:1 D/d on roundslings, and flags anything past 60° — who has a reliable, shareable reference or calculator you trust on deck, ideally one that handles 3-point and shifting apex without Wi-Fi? I’m happy to trade my template and notes from last month’s 12-point truss in Phoenix if that helps.
