I am thinking along the same lines. Although I am going to add mast in later. Probably run the DHB at 600 for 10 weeks w/ my test equal to or a little higher and then bridge into tren 500-600/test 400-500/mast 400-500 for about 8 weeks.
With you being more advance in cycle history, I would plan a more aggressive cycle for you as well. I would probably cut the first half to 10 weeks instead of 12, add tren and mast longer duration as well
You could also bridge the tren, say week 6-12 and then run your mast P even higher and more aggressively
