Coming from a newbie to mountain biking, I went clipless after 2 weeks of owning my bike. I love the clipless pedals. I have a harder time clipping in than clipping out for those that think you can't get your feet out. I've only wrecked one time and couldn't get my feet out in time. I wreck a lot so that one time is like 1 in 50 LOL. Anyway, It does take some practice but man Is it worth it. You can adjust most clipless pedals so that your feet aren't locked down with 2,000lbs of force so you can't get them out when you need too. For trail riding it's a must in my mind and has made riding much more enjoyable and easier in the rough sections. Just don't be skeeert, if so, go back to mommy's house for some kool aid and cookies.....
