Hello folks

This is my first post here.
I currently live at Japan. I will fly within Southeast Asia or Far East occasionally.

Right now I have CX AM and ANA MC.

I have ANA MC with Edy function. I've been using it when buying something at combini. I get 1 miles for every 200yen spent.

I also have SMBC standard credit card. This is my first Japan credit card. I got 1 point every 1000yen spent. But if I convert it into ANA miles I only get 3 miles or 333yen/miles.

I'm thinking about change it into ANA card, but I'm confuse which one to choose. The list is here

My account is at SMBC, so I think I have better chances to to get either SMBC ANA Visa Card or SMBC ANA VISA SUICA CARD

This card will mainly used for:
- Pay bills
- Buy ticket (1-3 times a year for business purpose). 1-2 times a year for holiday (travel with wife and kid)
- Shopping at nearest supermarket for daily needs
- Shopping at online store (rakuten/amazon/etc)

So my question is:

1. Which ANA card to choose to maximize miles from my spending pattern?
2. My wife and kid don't have AMC yet, I wonder if I can get miles from their flight? It seems unlikely though
3. I have a point in my SMBC card already, say, if I get new SMBC ANA card, can I transfer my point to my new card?

Thanks
