Next Purchase - HELP!

[nickb732]

I'm considering my next Rolex purchase. I know this is a controversial topic, but this is mainly for investment. These are Rolexes I know I'll want in the future, but am not particularly lusting for now.

My current pieces: 116520 Black Dial, 116710LN

I'm looking at either the SS YMII, or a WG Daytona (probably Panda Dial)

These are the factors I'm taking into consideration, in order of importance:

1. Resale value
2. WG Daytona available far below MSRP, and the YMII is very expensive for an SS watch.
3. I really want to try out a full gold watch, the weight and wrist presence comments from TRF members are really whetting my appetite.
4. I already have an SS Daytona, I do not want to sell it but I know it'll probably not get any wrist time if I get the WG.
5. Relatively high possibility of WG Daytona being updated with a ceramic bezel soon.

Ideally another option would be a TT YMII, sort of a compromise, but I doubt it'll be good in terms of an investment.

Please help me out! The more detailed the reasons, the better, based on my five factors above, if possible. Please feel free to suggest other watches/brands as well.

Also, opinions on DD, soon to be released BLRO and Everose Daytona on strap please!
