Now the A100 is gone my CF Sandisk UltraIII 4gb is a chew toy for big wolf. I have a standard Memory Stick Pro Duo 2gb in the new A550 and I'm thinking of buying.

1. GENUINE Sony or Sandisk Memory Stick Pro HG 8gb

2. An SD 8gb card similar to the Sony HG model

What advantages will the Sony PRO HG give me over the standed Pro Duo model? I want the same performance my CF Sandisk UltraIII gave me for sports shooting. Speed for downloading images to the PC isnt really a concern.

Wish I could have kept the CF card............dam Sony. My wife has a Sony point and shoot W290 so I dont really want to go SD unless I really need to.
