I just got in my Vibrams from DGC and I discovered that I ordered an Ibex (not an Obex) in 158M, and an Ascent in 158M. I have a 178M Ibex that feels noticeably heavier and spins much slower when I'm just casually tossing them into the air and catching them. This is my first time to get discs in the 150 class range, so I'm pretty excited as to how I'll throw them. I usually get discs in a range of weights when I get a new mold, at least with midranges,fairway drivers and distance drivers, but usually stay in 160g and up.
One curious thing, too, is that on my Ibexes, their ratings for turn and fade are reversed. I don't have them in front of me, but I believe the heavier 178g has the rating listed on Vibram (5/7) but the 158 is reversed (7/5). Has anyone else noticed this, or do the ratings change dependent upon the weight? AFAIK, the 158g Ascent is the same as listed.
On another note, I wear Five Fingers, so I always call them "Vee-brums," with this being an Italian company and all, so it makes me wince a little to hear Vibram pronounced as "VAi-bram" in the disc golf videos. I used to pronounce it this way until I found out that Vibram was an Italian company. Is it okay to pronounce it this way since I'm in the US?
