I used craig proctors sytem and looked at forte's what i have found more important than any system is how many people in my area are already using this strategy.Usually the first few to try it and pioneer become known for it the rest are just seen as the same which dilutes the effectiveness of it.
See what the tp's are doing in your area,if you want to foarm a sub. make sure an agent doesn't have market share controlof it already and make sure homeowners aren't already getting this same stuff in the mail.
It's funny i get about 5 pieces a week from the i am your new realtor junk in the mail,then i make predictions on how many weeks before they go broke mailing these out. good luck
