1) The T2 has only one ball nubbin - the J2l, S6 and others have two - this could be the reason that some have had no issues.
2) I honestly do not understand running such a heavy hopper on a pump. A revvy would do the same thing and take all the weight off. I don't run a feeding hopper at all - and rarely - if ever - have feeding issues. You naturally shake the marker as you shoot it - I don't think it needs to be force fed. It is a lot of money I could be spending on paint... IMHO.
