EDT by Charles Staley, as well as its various forms and his other stuff.
ABBH I & II by Chad Waterbury, Quatro Dynomo may be a great fit as well as his other stuff.
OVT by CT is a Killer as well.
Man it just depends on which route you want to go. Go to the library and either Go under the training articles section or search all the article by author.
I personally have been doing CW's programs up till about a month ago. I have now switched it up for my first go at EDT and Im loving it.
I say just mix it up and find what works for you. Keep it fresh challanging and fun. Oh and since MASS is the largets concern you really need to Look at your diet. If you arent eating you wont Grow!.
Hope that helps ,
