I'd just like to give a big shout out & recommendation for Josh Sowerby, aka; Oliverstacy.
I've been getting Josh to twist up srtings for me since he started making them. I've probably had 13 or 14 over the past few years & I have to say, every single one has been a work of true craftsmanship.
I'm not really one for throwing recommendations around, willy-nilly, but a couple of really good folks just deserve public praise. Bob Morrison is one, Oliverstacy is t'other.
His strings are always, always perfectly round, the correct length, have great loop sizes, are nicely served & usually made & delivered very quickly. My last 2 were ordered on Monday mornings & delivered by Thursday. He has an amazing array of colors and serving sizes & materials. He can pretty much twis you up anything you need, from skinny 6-8 strand strings for my stable of Morrisons right through to monster 18+ stranders for my bowfishing bows (they get a LOT of abuse in the boat & cut strands are the rule, rather than the exception!)
All in all, if you need a great string at a great price, give ol' Josh a shout. I
promise you'll not go wrong.
