I've bee playing about a year and have run into the same problems. I can really recommend what the others have said about discing down. You're better off landing on the fairway 75' short of what you could get with a driver than chucking into the woods. I've had to find a mid that works for me there, I have trouble keeping certain mids low. I've added a disc to my bag just for doing wooded shots. Find the mid that you can get the straightest and go with it. I had to stand at a tee on a wooded tunnel and throw my entire bag five times through before I got it. I can drop my mids on the fairway 9 out of ten and my driver about 3 or 4 out of ten.
