Hmmm, oak-aged IIPA. Intriguing.
I did a barrel-aged Scotch ale (okay, so it was oak cubes soaked in bourbon added to the secondary) that did pretty well in competition. I am currently soaking cubes in Crown Royal and another batch in some single-malt Scotch (I can't remember which one, but it's pretty good). I have 5g of Scottish 70/- that will get split between the two. Trying to hit the I&G style, like Revvy was mentioning. I need to find a vanilla bean too. Maybe I'll use a few ml of vanilla extract instead.
