I've had some lovely English x Satin Angora kits, with lovely fleeces, the best of both worlds; and of course, sometimes you get the worst. You won't get satin fiber the first generation, it takes two recessive satin genes to make satin fiber. But, you may still get nice fine, soft fiber, and probably more than you would normally get from a purebred Satin Angora.
I've been in your position, trying to balance between waiting for a buck to mature, and trying to get a doe bred while you still can. I generally lean to the side of 'get the doe bred'. Once she has had a litter, even if she loses it, or it is to a buck that isn't your first choice, she should be much more likely to breed again next time, when it can be to the buck of your choice.
