Routing halyards to cockpit

I've got a DS-I with a cabin top mast hinge.
I would like to lead both the main and jib halyards back to the cockpit.
I was planning to install a pair of blocks on on the cabin top on opposite sides of the mast, from which I would lead the halyards back to cam cleats on the edge of the cabin top.
A couple of questions:
Do I need to reinforce the cabin top with a wood at the mounting point, or are metal washers sufficient reinforcement ?
Any recommendations on the positions of the blocks or cam cleats ?
The front edge of my cabin tends to flex more than desired when a crew member is working on the cabin top. I was planning on reinforcing the edge with some wood at the location where the cam cleats would be installed. Any suggestions as to how to attach the wood to the underside of the cabin top ?
Thanks
