Strong, childbirthing hips. How do you bone them?

Okay, so I've decided tonight is the night I start to rig my new figure. The least favourite part of anything 3D related that I've yet to experience and my hat is definitely off to people who have a talent for rigging. You are like wizards to me.

So I humbly seek the advice oh great and mighty ones.

The figure has very wide hips and I was wondering how do I bone them? Do I bone them straight up and down like I would with a regular proportioned figure or to I angle the bone as if it was coming off a wide pelvis?

In this image which way would you bone the figure? A, or B?

    Holding off on the hips for now but got most of the upper body boned. I do have a question about boning the tail though.

    Where do I parent the base of the tail? The tail comes out of the figure above the buttox. Do I parent the tail bones to hip, pelvis, abdomen, or abdomen 2?

    Well in real world terms tails are the spine just carried on. So I'm thinking hips.

    That seems logical.

    If I find after I weight map it that the bone doesn't work where it's parented can I reparent it to another bone without affecting the weight map?

    Yes, though you may well need to adjust the weights to account for a changed origin (if the non-zero weights start away from the centre point you can get an odd ridge; if you have weighting "above" the centre point parts of the emsh will go the opposite way to the main bend).

    Okay that's good. I didn't know if weight maps are like UV maps where any change busts them up. I don't mind modifying them but I'd hate to have to redo the whole thing from scratch because I made a change in the parent order.

    I've parented it to the hip for now. I think it's either got to be hip or abdomen, so I'll see how it works with hip. Almost got all the bones in place. I'm going with a straight thigh bone for now and if it doesn't work I'll try one that follows the angle of the hip.

    I'm doing the weight mapping now and I'm running into a number of hip related problems. The figure is very bottom heavy, very wide hips and a pear shaped figure with big round bottom and belly. When it bends around the belly and hips it bends very poorly. I didn't have the problem to this extent when I made the chibi figure but the chibi wasn't quite as extreme in those areas as this imp figure is.

    Are weight maps alone not enough to get a nice bend in this area? Will I need JCMs or these bulge map things to do this right?
