Thanks for the input everyone. I think I'm going to order the ACR Firefly 2. It satisfies my need for light weight and small size, but does not compromise on light output. I will also equip all lifejackets with the smaller ACR C-Light. While I'd love to be able to put high output strobes on each lifejacket, cost is an issue...flying is so rediculously expensive it burns up far too much money allready <img src="/images/graemlins/crazy.gif" alt="" />
