mint was trying to keep up with charts and the last few they did were more of a chart for PLH to show some variances that people may have reported within the runs. the 2nd run has the most variances bc that was basically a "trial" run to see what could be done with certain blends.
i can tell you the heavy orange 3rd run apex are straight to fade and glide forward plenty, 3rd run apex's are a favorite of mine and lots of others if you dont mind dome. the 3rd run pink eternals are about the same but maybe a tick more hss but not much. the 4th run eternals are all about the same as far as the straight to fade flight goes without turning much for most players unless you are a power thrower.
id say your best bet for the straight to little turn alpha is going to be the 2nd run (open jar) nocturnals, 3rd run purple apex and 4th run purple metal flake eternals. keep in mind though, the flight characteristics of the alpha represent the straight to fade flight path, not many are understable but they do exist, its just not entirely too common. i would recommend finding an alpha you have and know how it flies and then compare PLH to others in store if you can. otherwise 2nd run nocturnals are your best bet for least stable of this run that you can purchase online.
there are earlier runs that are straight to understable out of the box but theyll cost you if you have to search online. specifically the 2nd run sublimes, 2nd run pearly green eternal, 2nd run pearly pink eternal, 2nd run purple apex.
if you have any more questions, feel free to pm me or ill respond when i can on here
thanks for supporting mint.
ps ive included the charts that can be found on the mint discs website under news/blogs. nothing new has been updated atm for the most recent runs but these should cover the 3rd runs.
