Best handles for Lifeline/B-Line tubing?

[Judith L]

I have the hard handles which go with Lifeline/B-Line tubing and wonder if the softer or "comfort-grip" handles are better. Or rather better for some exercises -- which?

And where is the best place to buy them (other than Beachbody)? I looked on Mary's site and the shipping is more expensive than the handles...

Thanks.
