I used to use plaited because they look so lovely, but they have absolutely no grip when they get wet so that could be a factor when making your decision.
I prefer laced, but it's your choice really. I don't like the bulkiness of rubber reins, half rubber are okay though. I'd get a show pair and a daily pair, but what kind of reins is personal choice
I love the look of both plaited and laced reins, but find them both a real pain to clean. For me, save them for best and get half rubber for everyday- good grip, not too bulky and easy to clean.
