M_Boats: Quick Release Backstay Lever

Seems like almost every M-17 owner leaves the backstay and shrouds attached when trailering. With a CDI furler on my forestay, it would be difficult to pin the stay to the bow fitting, unless the backstay is loosened. Seems to me that a Johnson Quick Release Lever would allow the mast to move forward enough to easily pin the forestay. Then a quick closing of the lever would tension up the backstay. Does anyone out there do such a thing? Is there any danger of over-tensioning the shrouds if they are left attached without loosening? Thanks, Mark House World's Slowest M-17 Rigger
