Upon advice from many sources, including many helpful MR members, I bought some CactusV4s a while back. They have been working GREAT, except for when I am trying to shoot snowboarding/skiing out in the elements, in which they turn to absolute TRASH. They misfire NONSTOP, and sometimes in the cold I need to slow my shutter down to 1/15th to even catch the light, the sync is so bad! These problems aside, I need to upgrade ASAP so I don't spend the entire winter snow season pulling my hair out in the cold. I have heard good things about The PCB CyberSyncs, so I am considering the -CST Transmitter ($60) -CSRB reciever ($70 per) Anyone have any experience using CyberSyncs in the snowy cold? I'm talking Minnesota cold, like -down to -20 F. Or should I just splurge on a PW Plus II? Are the pocket wizards really worth the extra dough? ---I have no interest in any TTL auto crap, I like setting everything manually and dialing it in. Thanks guys!
