We are going to Hawaii next week and I've been thinking of taking my Meridian 45B point-n-shooter on this trip. Up to now, I've been always using regular 2-sheet holders with this camera. However last week I bought three grafmatic holders and I've been contemplating to take these instead of the regular holders to save the weight/volume. I have not used this type of holders before and I don't know how well these particular holders work. I'm a little worried about using new to me equipment for what might be valuable photos. So I'm looking for advice: should I or should I not take these instead of the regular holders? What are the gotchas with this kind of holders? Anything I should check and or do with them before the trip?
