I've been using a few tweaked samples of the GT125 for a while now and was fortunate enough to be given a new final version by Mike earlier this week.
Tapers, production processes, coatings, colours (and everything else) are under constant evaluation. The latest incarnation of the GT125 comes in a muted orange colour that is very visble but far from Hi-Vis, nice fishing colour for all situations. The material the line is made from has been changed slightly and a new production process has been empolyed that gives a very smooth & extremely slick finish. Straight from the spool the line feels extremely slick, almost slippery and very supple.
Yesterday, I threw my longest ever measured full line cast with it. Today with no tape, the backing knot was rattling up the guides every cast and all casts turned over very well, it really shouldn't be so easy to cast a 125' fly line and get a straight leader
I fully expect new records to be set with this line.
At fishing range, nothing has really changed, turnover is still positive, predictible & easily manipulated even at the extremes of normal fishing range.
Very very pleased with the small tweaks we have made, without doubt the best long head fly line I have used.
Cheers
Ben
