Kane, sorry it took me this long to chime in here. I have used HST in the past for mass and I grew decently, although if I ever do it again i will cut back on bi/tri work. My legs/chest/back seemed to grow but my arms just didnt. Ever since I hit 17" it seems like they just stopped growing. I will admit I started really focusing on strength and not mass at that point, but they should have gained something ... overtraining is a bitch hahaha.

If you have a look at my journal, I have been using a custom routine for strength in certain areas, and a hypertrophy in others. Just cold measured my arms and they are 18.5" (although thats not all that acurate, I did it myself). I have very little volume in my routine, mostly because of my injury, but it could be adapted for anything really.
