It is not that big of a deal to take out two shroud pins when I take the mast down.
One forestay pin right? Why would you remove the pins in the shrouds? I would leave everything attached. Unpin just the forestay.
We tape everything at major events... in hot climates... residue is not a big deal, but we don't leave them taped for months-on-end either. Also, you should also have boots over the adjusters and pins.
