My seasoned 169g QOLF 1.2 has about the same flight path as my new 175g SOLF 1.1. I used to throw the QOLF 1.2 for all my thumber shots and I think thats the main reason it lost some of it's stability. I also picked up a brand new 168g QOLF 1.1, and that disc was a little easier to accidently turn over with unintentional OAT. I have since traded off the 1.1 QOLF and am now looking for a heavier QOLF 1.2 as my 1.2 that I have now flies more like a Wraith than a mini-Pred. It still laughs at most headwinds though
Back on topic, I have an Opto XXX on the way to me that I should be getting middle of this week. I am really excited to try this disc as I like what I have read so far about it. The one main gripe I have with my Preds is the shard edge the underside of the rim has. It hurts my thumb when I release thumbers with it, which sucks as it's my main thumber disc. I also just aquired a 171g flat top Star Firebird from a friend that I have been liking so far. When this XXX gets here it's going to be a 3-way battle for the overstable slot in my bag...Z-Predator vs Star Firebird vs Opto XXX. Only the winner will ride in my bag,and if the firebird or XXX win I will have to order a few more since I like to have backups of my favorite discs.
