While 3/16 is certainly durable but they're more prone to breaking off (or bend what they're attached to) from an offroad excursion because they're not very flexible. I and many others find 1/8" about as thick as you need. In fact the big boys use even thinner one's but they also have the budgets to replace them frequently (like every rally or even during a rally).
