Any test will work, preferably Test Enanthate or Test Cypionate (Test E or C) will work best due to its less frequent injections (twice a week ideally) as opposed to test prop (eod).
Using a longer estered version of test as mentioned will benefit you by being able to combine your injections together all into one. With Test E or C you will inject on mondays and thursdays each week along with the deca and eq. To put it short...go with test E or C. Let me know if you have any questions.
