Sniper Insight

Your current setup is being pushed mostly by geometry and accessory loss. Tightening cut strategy or pre-mapping trim can shave waste faster than trying to bargain hunt on material price.

Hidden Cost Leak Watch

High complexity counts can create repeated partial-piece waste.
Starter and trim overlap quietly snowball on large elevations.
DIY contingency is cheaper than emergency mid-project reorders.
