I don't know the specs on your, but I have 78 sq ft reacher on mine that is a LOT bigger than the stock jib. I have 4 years on it and have had no problem. BUT if you loose the forestay your mast WILL go down. No way around. I think you are OK, Just replace forestay and shroud every 2 years if you sail a lot. Also check swages ever so often for frayed wires.
Just my 2 cents,
Doug
