get both??? I can't help to love my Lat64 disc. It's the grip of them. I am in FL and it's just humid as hell everyday. You sweat as soon as you leave AC. But since switching to Lat64 disc I haven't had to use my birdie bag once. I love my buzzz a whole lot. And the core doesn't really fly like a buzzz at all for me. But it does fill that same void. I can throw my core just as well as I can my buzzz. I like the buzzz mold more....but the grip...the grip keeps bringing me back to the core. But I mean have both. You will find a situation for both of them. Yeah they might fly the same and both do the same job. But you might feel more comfortable throwing each disc in different situations. So if you have room for both....carry both.
I have a buzzz and a core. I love the core, I can rip it out on a hyzer and it will flip flat and glide for decades. Its similiar to the buzzz though, its definately slower but if you rip it out flat, it will turn over and sail. Took me a few to get used to it. I can throw it as hard as I want now, but more power equals more hyzer release.
I will however be picking up a classic roc, Im not into the feel of the normal roc though so I will stick with what I have.
Have you ever tried the Fuse by Lat64. I here its like a comet!
I throw the Core and a Roc. I carry three of each all the time, beat in at certain levels. I say have both since they compliment each other very well. I get more distance with the Core and it is very easy to control when throwing full pull shots but on the other hand the Roc just seems easier to throw more finesse type shots such as turnovers and shots were i need less power and more control. I also throw two different Roc molds, Ontario which is a great turnover or finesse disc, and Rancho which is more overstable and is very predictable .I have always thrown Rocs and the Core has fit right in my bag since trying it out a fews years back. Hope this helps a bit.
