some observations-- the other docs have given you good advise so i'll
just make a few points.

1.  don't be so fixated on the importance of base curve and diameter.
they are not that critical to the success of soft disposable CL
fitting.  your eye doc may choose a steeper or flatter base curve
based upon the tightness of the trial lens fit at your follow-up visit
but you are trying to be overly analytical about those parameters.

2.  you have also noted that your distance vision is not very clear in
non-toric lenses.  that is enough for me to suggest that you eliminate
consideration of spherical (non-toric) lenses regardless of the brand
or base curve or whatever.

3.  coopervision makes quite good products-- especially torics.  there
is nothing wrong with their products.

4.  it takes some time to get a good toric fit.  you need to try
different lenses, then have the doc evaluate their rotational
stability on your eye.  you should compare them to different brands.
don't get impatient and just jump on something because then you could
be stuck with it as your final prescription for a full year even
though it is suboptimal just because you were impatient when you were
being fitted at the start.

5.  you cannot just call up 1800contacts and tell them whatever
contact you want.  they need to see a valid doctors prescription
before they can sell you lenses.  they used to just sell patients
whatever they asked for without checking with the eye doctors (in
blatant violation of state laws) but after strong legal pressure and
the passage of new federal laws, they are required to get a doctors
prescription and cannot substitute any other brand.
