if the pellicle drops because it is agitated and it doesnt reform, yet you are letting O2 get into the beer, youll end up with nasty flavors like ethyl acetate ie nail polish remover

Only if you have air/oxygen in the headspace. I've never had an issue with dropped pellicles when I'm aging a beer in a carboy or better bottle with an airlock.

that is the catch though, I generally use a dowel or if I use an airlock it always runs dry, as long as I dont move the beer its fine, although you tasted how nasty a batch can be (my Flanders Red) when the pellice drops but O2 still gets in

Even the dowel doesn't simulate a full barrel in how much O2 can move into the headspace. I'd almost rather leave some loose foil over the carboy neck and let the pellicle do its job.

Waaaaaaaaay too much oxygen will get in and you'll have 5 gallons of vinegar after a year.

Thanks for all the info, again, guys. I ended up adding the malto-dextrine, then adding a self-toasting an oak dowel a couple days after. There didn't seem to me much of an effect from the malto-dextrine addition, but a day after the dowel was added, i started to get some head-space scuzz (sorry for the chitty phone-camera quality). Praise be to Oxygen!
