Layne Norton's Power + Hypertrophy Split

I've been using a slightly modified version of Layne Norton's split and I've definitely been noticing some results. I've been eating pretty clean and I never go overboard with the cals. 3.5 months in and I've gone from 183lb to 188lb with a noticeable size gain. My upperbody and lowerbody power has shot up as well: 225x4 on bench to 225x8 or 9. 225x3 ATG squats to 275x5 going as low as I possibly can. The only difference between my current split and the normal split (that's posted below) is that on hypertrophy days, I usually do 4-5 sets per exercise since I prefer high volume.

Here's the normal split (taken from http://www.simplyshredded.com/layne-norton-2010-training-series-featuring-paul-revelia.html)
