If I was doing that cycle with your goals, I would bulk for the first 4-5 weeks and then diet until the end. I can forsee a 10% increase in maintainable strength and 8-10lbs LBM over your last cycle LBM at your size. If you go in leaner, you can stay bulking longer and end up doing allot less dieting.
Personally I like to overlap my compounds instead of quiting one cold and starting another. Start the fina in week 5 so you will be rolling on it when you stop the dbol. At high dossage cycles this may not be a good idea but completely safe at your suggested dossages.
