A good trick with Rainbow tables is to disregard the following chars: , . / ; ' [ ] \ < > ? : " { } |

I did this with my rainbow tables and it only took about 2 months on 3 different computers.
Make sure your charset looks like the following:

alpha-numeric-symbol14-space = [ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()-_+= ]

also you will create 6 tables with 4 rows each. When I did this I get about an 80-95% of cracking 100 complex passwords within an hour.

your table format will look something like this:

lm_alpha-numeric-symbol14-space#1-7_(table#)_5400x67108864_1(row#).rt

Hope this helps!
