Honestly I gotta push back on that one. So many of those old timers make their point with a colorful line but the real math is in the sheave angles and what the load is doing on the hook, not how your wrist feels. Ive seen guys swear by the fishing rod thing and then still swing a load into a trench because they forgot the wind was picking up.

Wait, have you ever tried to go back and fix something after you've flattened everything? It's a nightmare... you lose all that flexibility, and if the client wants a tiny change to the stroke on a logo from three layers down, you're stuck recreating the whole thing from scratch. File sizes aren't that big of a deal these days with good drives and cloud storage, but time lost hunting for mistakes? That's real. I'd rather have a few messy layers I can tweak than one clean mess I can't touch...
