Below £100 in London you will typically find yourself with a WG who speaks little if any English. Keep in mind
At 100 around Old Street or E1, though, there are some dependable Polish women. But they are not stunning to look at like the Roms.
I'm sad that the Hungarian milfs have gone home or to Willesden. I did find that they spoke enough English, but were not necessarily pretty. Or young. Mixed service sometimes but on average (for me) VFM.
What's not really discussed so far I think is national correlation with 'likes'.
There used to be some Poles doing BB etc but it seems less now: OTOH I seem much more likely to get OWO/CIM with a Pole than with a Rom or Brazilian in my experience. Hungarian: bit mixed, more likely just OW. I think more Poles have allowed fingers too. British: bit costly but I've had fun with older ladies.
On balance I'd normally think a Pole at 100 or 120/hr is a reasonable TOFFT opportunity, they seem 'accommodating'' if slightly passive sometimes - but normally IMO pretty straight with a business negotiation. They'll deliver but not necessarily with passion, where a Rom will just tell you the profile is crap. And the profile will stay crap, normally.
Some of the recent pics of London BB Rom in the avoidance thread, they also show up in Bedford and Leicester. There seem to be many who advertise it, and unless its the tout the reviews on [unmentionable] suggest that they deliver. I was going to speculate that Volvic is dead now: he probably does deserve it - but it just seems that he moved to Watford.
