Thanks, Clarice, for your reply and the link. I just filled it out so hopefully I will get the packet in a few days. I was diagnosed one week ago and am so confused about the options that I am going crazy already. I will be happy to get the WTT list so I can call some people with ANs similar in size to mine (2.1 cm) to see how they arrived at their decisions. I see you went to HEI--they are on my short list so far. Did you also consider GK or CK? Thanks again.
