Okay, I was over simplifying it by saying you can ignore the wind by pulling out those specific discs. Of course you have to take the wind into account when selecting what disc to throw. Even something overstable with an incredibly predictable flight path is going to be affected differently in a tailwind versus a headwind.
I am in no disputing what your disc is doing, I am not there and I have not seen you throw, but I am not a noodle-arm (nor a canon either) and I do not get the XXX to flip. I barely get it to turn on a clean, flat release (175g Opto). I can force it over on anhyzer and it will obviously flip back into a fade, but regardless of conditions I know I can trust it. In a way, that trust reinforces the argument that it involves more skill than what disc you throw.
If there is a grand and over-simplified statement I am making, there are some great stable to overstable fairway drivers that can be trusted to get acceptable results despite of the wind. You may lose some distance, but you do not have to sacrifice much accuracy. The variable of wind may not actually be removed, but the variable of where it should land the majority of time despite the varying conditions is better controlled.
My order of trust in my bag goes like this (high to low):
Drivers - XXX - Force - Sword - Boatman - TeeBird - King - River
Mids - Drone - Roc - Axis - Meteor
Putters - I do not trust any putters in the wind. I had a Zone that was decent, but it was not that much shorter than my Drone and thus created a lot of overlap. I used to carry a Pig, but they had no glide in the wind which defeated the purpose of putting.
Fair enough! I hope I didn't come across as combative - I read over my first post and felt it was a bit snooty. The XXX IS one of the most predictable discs in a headwind, and maybe the wind was going faster than I thought when it was flipping. Being in NH, we don't see a whole heck of a lot of high speed wind...
