OK stringing with the Panthera is easy very slippery and a bit more stretch when tensioned.
Knots are fine and not as stiff as normal poly.
First impression when the restring is complete is how the string "Glitters" it does reflect the light!
First hit: A cold wet and windy night in Chippenham, First hit seemed a bit stiff then after 15 mins wow it just seemed right, control comfort and spin I like it already, didn't have power but I was expecting that but the control and comfort is really really good. I had to keep checking that this was a co-poly string! No need to hybrid this as a full bed is comfortable, you could add a softer mains (natural gut or a synthetic) for a power increase. As always your choice!
This is going to stay in one of my rackets until it breaks or the tension goes.
I will offer a full restring or hybrid for as normal £16 with this string.
(As it is a slippy string it may work in the open pattern spin rackets !)
Hope this helps!
