Deca and Tren are the absolute GOAT. If you want to run a shorter cycle, pick shorter esters; that is the key. If you want a longer cycle, then go longer but I wouldn't run Tren more than 8 weeks or Deca more than 12 weeks.
Test prop is a good one but watch out for post-injection pain. You want to make sure you are aware that that is a possibility so you may get bored with it.
