Dont read to much into some replies. This is a BB site and people have a certain expectation of body mass before use because we are thinking size. You are more sport oriented so it will be a little different for goals and usage so please bear with us and be patient. You may have to explain your situation more than once, some of us (especially me) have bad short term memory.
As far as the Deca, not advisable for what you are looking for especially a first time Test user. You would get to much bulk and probably bloat as well as possible sides and you would not know if it's the deca or test. It's a good idea to let the body get use to one thing at a time to make adjustments and know how you will react.
