All beautiful ladies, some of their weights are a little heavy but other than that its all personal taste. Might be a good idea to keep her shorter than yourself. Easier to handle and position. Personally for me I like tanned skin, some ladies can be quite pale. Well I married a Chinese woman so its my taste I guess.
If its sex your after more than photography, careful what face you get as it will be that face you'll be looking at. A slight smile or sexy expression will go better than a blank, disinterested or stern expression... If there's a deal for two completely different heads, this might be an idea as you'll soon pick a favourite for different situations.
My favourite was the first lady, but that might just be her dress LOL!
