In a way you are in a very good spot. Lichello first came up with AIM back in the 1970s and Tom Veale and some others jumped on the idea and quickly improved on it.
Then there were lots of others who had ideas (some good and some not so good). Over the years, however, the good ideas are still being used and the bad ones fell by the wayside.
I think most of the ideas that are good have already been brought forth and discussed on the main AIM board and on the old Silicon Investor board (I'm sure there are others that could be discussed, but the ones that have the biggest impact are already out there).
This is normal for just about everything. In the early going there's lots of activity and development and then, as the strategy matures, it settles into a stable state.
So you are in a position to take advantage of a very robust system that is being used extensively in the real world and has been tested by quite a few smart people.
Where investing systems are concerned, I think it is better to use one that is mature, open and has been publicly scrutinized and tested rather than one that is in a state of constant modification.
Lichello gave us a pretty good system and others have made it better, but now I think AIM has reached a point of stability that really doesn't need additional tinkering.
