9.81 - a bit pessimistic on the holding situation at the moment. The legendary 2 or 3 year holds were happening 8-10 years ago; recently people have been going from IOT to fast-jet OCUs with only a couple of months off total! Having said that, Valley is starting to clog up a bit, but I can't see a return to the long holds of yesteryear. Friends in the rotary stream seem to have gone through very smoothly as well, and not aware of snags at METS, so I would say you don't need to budget in any more than, say, 8 months in total for holding.
