I will give you a little tip. If you mount a block on your spreader for a burgee halyard, make sure you keep it as far away from the shrouds as you can. If you don't, you will be nice and cozy in bed one night and the breeze will swing around so that your burgee starts to twang the shroud. The sound will be so annoying that your wife will make you get out of that nice cozy bed and go on deck to take the burgee down! This will likely happen to you repeatedly until you get into the habit of taking all your flags down every night before bed, and even then you will forget..
On the bright side, I did discover some very handy quick release clips for the burgees so they are easy to remove quickly! They don't require knots or anything, they just grab the halyard wherever you want them.
