Do you use right twist thread in your left bobbin on your two needle machine?

I never have bought R-twist for the L-side needle on the double-needle machines . I just keep an eye-on that L-side when sewing and binding. I don't think any one man shops or small sew shops do. You just keep eye on the left side as you go and when you notice the thread twist getting shitty, You just drag-threw some fresh thread off the L-cone threw needle and keep going.
That said, Not All threads are equal in the quality and twist and bonding. 
( for example ) , I am just coming to the end of a case of A&E t70 nylon bonded, and good riddance. I won't run that A&E t-70 on the double-needles because the thread is inferior and the thread Twist and Bond turns to Crap Real Fast on the L-needles . So I picked up 20 lb. box of Coats brand t70 nylon bonded six months ago with the same Color Code# as the A&E . That case of Coats brand thread is So much better quality twist/bond, and it will run for long time threw the L-side needle before I have to drag threw some fresh thread .

When I bought my twin needle Seiko 339, the seller, who was an awning company, was selling the machine as broken.  Because after sewing only a few inches, the thread in the left needle was entirely unwound.  The awning company was trying to make long seams and it just didnt work at all.  Folks on this forum recommended right twist thread and that fixed the issue immediately, but the selection of right twist thread is pretty limiting.  I probably need to try some better, left twist bonded thread in the left needle.  Thanks.
