It is flying pretty straight for me now. I like the disc a lot. I don't think it is exactly like a Buzzz but it's pretty close. Think of a buzzz that has some fade to it. I typically use it for hole I would also use my XL for. It goes far and straight. I find that I turn it over more than the XL...but a little hyzer fixes that quickly. At first I didn't like the disc that much but it has found a way into the bag and I am enjoying it now.
I have the glow versions...they are 9 grams apart and both pretty stable. I use'em for Night Golf only. I don't know what to compare them too...no way a buzz..these Glow versions are too stable for that. Maybe a Champ Orc..that's what they remind me of at least.
I have a First Run Stalker and i use it for the long tunnel shots for turnovers and straight shots, it's like a buzzz on steriods and when they came out with it and the ringer i was satisfied with their performance, i wanna say it's like a TL but I don't really know any Innova disc's because i mainly throw Discraft....
Just don't let the words "Extra Long Range Driver" trick you. When I got my first Stalker, I foolishly thought I would get around the same distance as my other drivers (e.g. Surge, Avenger). When it didn't come close, I took it out of my bag. It wasn't until a couple of months later that a buddy explained that it wasn't a driver per say, just a longer Buzz. I now carry two, Elite-Z and Crystal. Great disc for straight shots! It would be nice though if Discraft changed the wording on the disc to "Extra Long Mid-Range Driver". But I'm just an amateur, what do I know? :)
All I know is that one of my buddies is deadly accurate with one of them. He's got a very spin oriented throw that he seems to throw with no effort and when he throws a stalker it just seems to hold and hold and hold and fall out flat.
I said to myself, "Oh great, now he can throw straight longer." :-) It's made me consider picking one up.
I was an xl guy til the stalker. I have plenty, at least one in every plastic. It is a very weight sensitive disc IMO, so if it's your first one, I'd suggest around 170g. My 170 that I first started really using is now great for annys but I don't know what to compare it to.
The problem with compareing it to other discs is it may limit your lines, thus not get you all the greatness of this disc.
I can tell you it's a longer buzzz cause when thrown flat and low it behaves simillar. I can also call it a slightly shorter teebird, my favorite shot with it is a slight hyzer in hand thrown ~25-30 ft high for 290-320.
I have a Z 173g tourney stamp and i usually use it for a headwind where i would normally use my Buzzz or Roc. The one that I have and the ones that my buddies have are all pretty stable. I'll also use it to throw uphill with some anny on release. I'm sure this will all change when i get it broken in more. Like Mark says "Z will last longer than your next X-GF"
