Springstay location question

[Brion Toss]

Hello again,
Got it. Your lower shrouds are indeed high, which means the forward one is well-positioned to keep the entire mast pulled forward. The jumper stay pulls the head of the mast forward, and is opposed by the aft-raked uppers. The jumper also pulls forward at the level of the radar, which is unopposed, but not likely to destabilize this mast. Finally, the jumper strut pushes aft, and is opposed by the forward lowers.
So the aft lowers don't have much to do, except to add to the load of the forward lowers. But again, not much harm done. I don't see what the springstay is accomplishing; try sailing with it slackened, and see if the mizzen shows any inclination to move around. I'm betting it won't. If the mast is stable without it, remove it.
Fair leads,
Brion Toss
