I have them , never had the first ones though so I can't really say what improvements were made . I bought mine directly from sprawls own website I can't remember what the handling charge was but the total only came up to 55 pounds and they took about a week and a half to turn up.I've been using them for a while now and I haven't really noticed any shrinkage and I've found them to be amazing ,no awkward restriction on movement and even during rigorous rolling sessions they don't seem to ride up for or fall halfway down your ass like the cotton ones seem to.
