I'll take 7 NC's and in the modern era a losing record to this point with 3 ties, but a 20-18 scoring advantage. Take into consideration that Texas is about 3-5 times the population of Oklahoma and I think we've done pretty freakin well.
Ah yes, those TX people who claim that we'd have no team if it weren't for players from TX. Well...as I tell 'em here...that may be true. You have a sizable advantage in population to draw athletes from, but the fact that you had to import me suggests you lack intellectual talent. Thusly, while conceding your point athletically, it should be more embarrassing to import smarts than athletic talent.
Here is a little blurb about the modern era stats: From 1945 to the present, the winning record still goes to UT, owning a 33-29-3 advantage. However, the average score is now at 20-18 in OU's favor. Using the following as a resource:

Yes, it's a few years out of date, so accounting for lost time OU is 4-2 against the nut sacks to the south which means the series is now 35-33-3.
