Thanks bro. It was/is a LOT of work, but WELL worth it
I started off WSB earlier this year and kicked it off very strict on how it's prescribed (mostly GMs for ME day, rarely deadlifting, blasting hams, not much quad work etc). For me, I found that with the changes I made (see my routine above), my progress moved along much faster. It was also more enjoyable for me. I do find that the core emphasis of WSB (blast your weaknesses) have proven REALLY well for me. I also found that I really like lower body workouts now (I didn't used to when I followed a BBing program).
Like you I am very much into bodybuilding. Actually I like both strength training and bodybuilding, and would eventually like to both compete in powerlifting and get some modelling work. So I do want to focus equally on both. I am a few months/years off both of those yet though
I find that the WSB style program works really nicely for bodybuilding for me with the tweaks I've made.
I think you should give a strict WSB program a go. In fact, I think everyone should. I think it's designed so that you can tweak it how you like. And from what I gather, even Louie regularly tweaks what he has his guys do. I find it works great for BBing too - let's face it, heavy triples and lots of compound moves are BOUND to induce muscle growth.
That's some nice lifts on SLDLs bro. I pulled a 200kg (440lbs) single on Monday for regular deads, but my SLDLs are nowhere close to that - I find I struggle a little with form on them. For grip, you could try chalk instead of straps - that's what I use. I can actually lift more with chalk than with straps.
For GHRs, do you have a lat pulldown machine at your new gym? If so, you could kneel on the seat facing away, hook your calves under the part your quads normally rest on, and do the GHRs that way (if you see what I mean). That's what I'm doing currently and it feels GREAT!!
