IIWY, I'd bottle sooner rather than later. I tend to have more problems with bulk aging when the beer in question is rather high in ABV...meaning, it's harder to get the bottle fermentation going the longer it sits. I still have a bunch of bottles of a barleywine that are very hit-or-miss when it comes to carbonation, and it was a batch I bulk-aged for 3 or 4 months. I even repitched an entire reyhdrated sachet of new yeast at bottling. I mean, you can do what you want, but my new rule of thumb is, unless it's a lager, I'd rather age it in bottles.
