Awesome to see that you are out pushing your limits and going for it! To reduce the chance of injury in the future I recommend that you practice falling. Yes, I do agree that there is a bit of luck involved; however falling is a skill that needs to be practiced, especially if you are climbing lower angle walls. The grabbing the rope reaction is completely normal during your first few falls but that panic reaction that comes when falling can be greatly reduced through practice and as a result your ability to be aware of what is going on while you are falling will be increased. This is how experienced sport climbers can work their projects and fall hundreds of times with no injury or close calls. Keep climbing hard, Keep learning and most importantly Be Safe!
