Thanks Miker and others. I also have the same system for reefing the lines and cleating them off, as described in your reply, but this does not reduce the mainsail at the mast - hence my question about using the rams horns. I think that the option of removing the locking pin is not the best option (although I agree if it is to be used, a lanyard would be a definite "must") so there must be another way to reduce the mainsail at the mast, in order to truly (not partially) reef the main. If anyone reading this has any other ideas they would be most welcomed.
