Sust and deca for 8 weeks is way too short to see any real progress. 16 minimum I would say, and I would also ditch the t-bol and instead finish the cycle with winstrol or anavar.
Fyi, you mentioned adding the tbol for cutting. The drugs don't actually make you cut, your diet does. You can bulk with any drug, and cut with any drug.
But what you can't do is try to bulk and cut on the same cycle, it never works
