Chalk and cheese comes to mind, especially given different nationalities.
The solution to me is to go for an english girl with a body like OLA. Ive always found EE girls to have a bad attitude, poor communications, not having a good command of English or choosing not to understand and also a difficulty in offering anything other than a deadpan face.
Also split the age difference from 24 and 47 and go for a 'late 20's' girl rather than a young fit girl who doesnt have to try because they know they will get business on looks alone.
There's not that many English girls with a body like Ola who have a history of decent feedback and for that price range-that's sadly the problem.
My experience with EE girls hasn't been that bad and has sometimes eclipsed some of my best ever punts with British ladies. My natural caution towards seeing anyone new is heightened when I consider seeing an EE girl and I think there are some things to monitor that can help to sieve the bad ones from the good ones.
It's also a bit unfair to lump all EE girls together, Czechs, Latvians, Poles, Romanians, Hungarians etc are all different and if you do your homework then you can find girls who do not move from town to town on a weekly basis.
Ola's service isn't terrible. I'd mark her as a 6.5 out of 10 and I am VERY fussy.
