I haven't taken a hard look at LD-AIM. Recent goal has been to build a portfolio of stocks to try and capture more volatility than ETFs but also maintain equal lower levels of risk. Maybe LD-AIM is a way.
For your weekend reading, in case you haven't already, here is the link to the LD-AIM calculator from Tom's site... http://www.aim-users.com/aimlodown.htm
Also, FWIW, I run a separate program for each holding, and a common cash reserve for all. It is currently around 30%, near all time high percentage.
