    I'll start by checking the current state and the piece geometry to plan a good layout.

    I have all the geometry I need. My plan: an original out-and-back design at y≈40-52 (staying clear of the lake at y55-75), with a chain lift to z=288, a 176-unit first drop, vertical loops, corkscrew pairs, a half-loop pair, airtime hills, banked turnaround, and a western turnaround back to the station. This differs structurally from "Time Twister" to keep similarity low. Let me start:
