I just can't compare Jade and Linda properly, as I asked them each for a very different style of service.
Jade knew that I'd literally just stepped off a 10+ long haul flight and was severely jet lagged. I asked her to go easy on me, she delivered this with aplomb. She dictated the pace, starting off slowly and sensually, building it up as the booking progressed. She's gives a great line in banter which I really liked, not overly talkative, she just eases you along with encouragement.
For Linda, after reading the reviews, I'd deliberately hit the gym just before hand, consequently I asked her to throw the kitchen sink at me, and to be honest, after the best part of 2 hours, I was hanging on for dear life at the end which was really enjoyable.
Physically, for a 40 year old, Jade's bodywork is in very, very good condition and she's got some engine on her. As VW has said, Linda's mid 20's, and like an F1 car, lights out and it's away we go, full on from the off.
After seeing them both I wouldn't bother choosing, just see them both, I plan to revisit each of them.
