My own experience recently with
www.amoi2u.net was good. I did outcall and the rates were reasonable (RM450 for 3 hours) compared to RM700/800 that some other sites were asking.
I chose Ling who hails from Hanoi. Tall at 1.68m with nice curvy shape - luckily I'm 1.75m and can match her in her killer heels. Really good GFE and attitude and loves kissing. I had such a great time that I opted for her again the next evening. I was tempted to try one of the other Viet girls in this stable who look really good too but I stuck with Ling since we have a great chemistry.
We still message each other now and I'm looking forward to going up to KL again soon.
So, for Viet FL, this seems like a good bet since you are likely to pay at least the same rate or more for 1 hour short time for FL at Beach Club or Thai Club - and that can be hit and miss too
