Mileage Run Discussion - Mileage runs out of Houston

Is ITA Matrix the best software to use to find mileage runs, or do you need a travel agent friend to book for you? I'd like to try some out of IAH since my next actuarial exam isn't until November.

post a detailed example or two of trips that you would take if you could book them....might elicit some help.....post dates, flt #s carriers....
