@Kev Gladly!
I plan on writing my formal review in a few weeks, but I did exactly what you are describing: 4 weeks of Giant, 3 weeks of KSK, and so on
This is how I organized these blocks:
Giant 1.0 with 2x24kg
KSK 1.0 Phase 1 with 28kg
Giant 2.0 with 2x24kg
KSK 1.0 Phase 2 with 28kg
Giant 1.1 with 2x24kg
KSK 1.0 Phase 1 with 32kg
Giant 3.0 with 2x28 <------This is where I'm at on my 3rd week
I never lost anything in the snatch with 4 weeks of Giant. In fact, when I started this whole process in the Spring, 32kg was a 3RM. It is currently sitting a very comfortable 12RM
