Humm ! This is getting a little bit out of hand. I hope he will not be irritate at me for spilling the beans.
Won't you (potentially) overload the bow areas running all that tension down to the forestay first ?
No, because any tension put on the spi halyard in this situation will lower the tension in the forestay by the same amount. In effect, the load on the bows will remain unaffected. That is just the beauty of it.
