This is currently my favorite forehand power driver. Bombs out of the hand and the K1 plastic feels fantastic. Kastaplast has some next level quality in their molds. I feel it has more turn in it than -0.5 but has a nice, strong fade at the end.

I absolutely love my Guld!! This thing when I first got it was pretty overstable, however when I would rip it hard I'd get it to hold that .5 for a bit. I use it a ton of spike hyzers and long fades. It's definitely a perfect disc for those aspects 

For being a 13 speed, I figured I wouldn't have the arm for it. It is definitely more understable than the numbers suggest, but it is still a great disc. Obviously K1 feels amazing, and this disc is my go-to forehand bomber. I can really crank on it and know it will still fade at the end even if I turn it more than intended. It doesn't feel the same as some other 13's though, as discs like the Nuke or Boss are significantly wider.

I have both a first run and a stock run in k1

This is a great distance driver

my average drive is around 380'-420' 

i had been looking for a slightly more overstable compliment to my lucid raider (has the same numbers as this but flies more like 13,5,-1,2) and the guld is a perfect fit for me. almost like a raiderX in kastaplast terms.

 I'd say the first run fits the numbers perfectly for my arm speed, thrown flat it'll slide right a touch before having a strong/dependable fade. The stock run I have is more overstable (pink translucent k1) probably flies like 13, 5, 0, 3-3.5 for me. great headwind compliment to the first run. if you're looking for a dependable distance driver, the guld should be on your list to try, k1 plastic is top notch so these have earned a spot in my bag for the forseeable future.

This is exactly what I've been wishing for out of Kastaplast for years. This is a truly reliable, slightly overstable distance driver.

First throw is like a nicely broken in Star Destroyer. 
I max out forehand around 450' and this quickly became my absolute go-to distance driver for power forehand shots as it handles torque with the best of them. I can only throw 370' backhands and it's hard to get the flight at that lower power for me but in a headwind, it does the job fantastically.

K1 Line plastic is still as good as ever, and they finally have the distance driver to match. 

This disc is pretty great as far as overstable high speed drivers go. I bought this disc in hopes of finding something that could fill the space between my Nuke and Destroyer and this was pleasantly surprising. I specifically wanted something a bit more capable of fighting wind than my nuke but with more distance than the destroyer and this really does do that. My first throw with my Guld was, to my surprise, about 40 feet further than my usual max distance at about 530. I suppose this extra distance may be attributed to the rim being a little small for a 13 speed at 2.3cm since I have a hard time getting a good grip on the wider max width rims that are common on other 13 speed discs. The Guld, much like my car, has 3 speeds; Here, There, and Gone (Gone in the sense that I let it fade out left into some trees and I couldn't find it so now its time to buy another one :/ ).

My review is based on throwing 2 different weights, 175 and 171 in the first run mint color. As a person who maxes out distance in the 375 range, I believe this disc is extremely accurate at the flight numbers - where Im getting the smallest flip up to flat before fading out. At 171 I've noticed a bit more turn. This should be the stable distance driver people have been asking for since the GrymX inconsistencies.
