Bulk aging...secondary, tap-a-draft, or bottle ?

Brewed up a big English barleywine 20 days ago; today I'm putting some other, low-grav batches into my tap-a-draft bottles to carbonate and condition for a couple of weeks and am going to be doing one of the above with this barleywine. This one was way up there, over 1.103 I believe...IF it's actually hit FG (I put this on top of a washed, healthy yeast cake from a recent bitter) should I...

a) put this in tap a draft (6L rubber-sealed screw cap) bottles to condition/carb until fall/winter
b) put it in bottles
c) put it over into a secondary, and choose my next route in a month

Basically, I have all my equipment out today (and time, which is usually very hard to come by)...if it's actually hit target gravity, should I just put it away, or will it condition differently/better if left in another 5 gallon carboy a month or two longer? Also, if I screw the caps on really tight, do you think I have to worry about oxidation in my tap-a-draft bottles? I want this to actually make it to the cold days of this fall/winter, as I put a lot of work into this batch. What say you all?

 

Yeah, it's a substantially thinner plastic than Better Bottles...this is what I was concerned about; for beers I turn around fairly quickly, it's no big deal, cos they're consumed before serious oxidation is a problem, but this wouldn't be consumed until winter....if that's the case then, what about bottling? If I bottle in 22oz bottles, will the beer suffer (again, if at terminal gravity) and should I instead do a secondary?

 

My original gravity was 1.102, my gravity at this point is 1.024...it's actually about a point lower than I was expecting, so I'm relatively certain it's done...decisions decisions...

 

Wow...I've also never tasted a big, burly brew super fresh...I hope aging does some good things to this...booze and dark fruit, anyone?
