I like how 5 was set up as well, its just not a reachable par 4 from the back tees, and in some ways, thats a bit of a waste for a short par 4 like that. As far as age and length, I'm 27 and from the back tees at Matt Springs, I hit driver into the left side bunker on 2, driver to 150 yard out on #4 and had inside 200 yards to the green on #16...so...take from that what you will. 
Hope to meet up with you some day.
So 19 years and maybe 60 yards on a good day. We'll have to meet up and I'll bring ear plugs to wear on the tee!
For what its worth, I don't use one of those really loud clubs. I've actually got an older model driver (not too old, like 2007) that is a smaller head and is not as loud. Though I am considering getting another driver, but an Adams Long Drive model. So that shouldn't be too loud at normal/fast club head speeds.
So, no need for the ear plugs. But I still hit is a long ways.
