Hi everyone!! I have been lurking around here for a long time though I have only started participating recently. Hoping to recieve help and guidance from you amazing people! I am in the process of designing a high quality work tote which has a dedicated padded sleeve for a 15" laptop. Naturally the bag will have fairly large dimensions and will be heavy once the laptop and rest of the things are in it. Considering these two factors, would you prefer the bag to have standard handles that can snuggly fit over the shoulder (such as in the picture below) or would you rather have shorter handles and a long detachable strap? Any other comments regarding shape, color or anything else will be highly appreciated!
