Best Verification method???

Ladies- Which is your preferred method of verifying a guy?
If it's a verification service, which is the best for you?

Guys- Which verification service do you prefer and why?

Thanks

I have had many over the years including RS2K, Date-check, P411 and TER White List but the only one I use now is P411. I do have TER WL mostly for the reviews though. The majority of the ladies I have dealt with around Iowa prefer P411.

P411 is probably the most common one around Iowa. I check everyone through verify him and safe office as well as those tell me who have been blacklisted by other providers.
