Strome is the name Locharron gives to it's 16oz tartan range of about 500 ish tartans.
As far as I know no one else uses that name, so if you have got a kilt in Stome fabric it can only be from Lochcarron. Not sure what you mean by pokey bits, perhaps the sample was a well used sample and felt a little smoother. Who made your kilt? I'm always happy to tell the customer exactly who wove the fabric,to me it's a mark of quality.
