Hello Squash,
There are two main ways to use AIM depending on the stock of interest.
1) Tune AIM's parameters for use with a relatively non-volatile stock.
2) Use standard AIM parameters for a volatile stock.
Over the years I've found that option 2 works better and is easier to implement (although option 1 still works in many cases).
While both options can beat B&H, my suggestion is to pick high quality, fairly volatile stocks for use with AIM. You might also decide to use some other investment strategy for the your non-volatile holdings (i.e. diversifying your investment strategies as well as your assets).
As Conrad already mentioned, most people don't use the B&H strategy, rather they use Buy, hold for a bit and then sell.
