Matt,
The mast was leaning so far back that there must have been more than a foot of slack in each shroud. That is far more than necessary to connect the shrouds to the lowest hole on the adjuster. Since the forestay doesn't determine the rake, only the lowest point to fasten to the adjuster, I don't understand why you would add a second 10 hole adjuster. Leaving slack in the shrouds as you described means not tensioning the jib halyard enough. Are you depending on the main sheet tension to keep the mast in the socket? If so doesn't that get dangerous when manuevering like coming about?
