Rws 48 T01 trigger .177 cal

Ok guys, a few questions to the above. A good friend is gifting me this nice classic. Due to health problems he is down sizing and want me to have it. Will be here in a week or so.. Been searching the forums and need a few answers.

1. Some guy think the t01 with ball bearings is the best among the t05 and t06. 2.The next guy switch the t01 trigger and piston to t05 setup. 3. Next guy switch from t05 to t06. Gun is a safe queen. Been setting for 2 yrs. Im thinking jsb 10.3 because or bc and let her rip. Need answers and opinions. Thanks in advance.
