Primary trade-offs are dealer-only distribution (opacity on pricing), higher curved-lift costs ($9,000+), and longer lead times for Helix custom rails. Best suited for homeowners who prioritize customization and US manufacturing over immediate price transparency and can absorb $7,000–$12,000+ investment.
