Just did the same thing last year, happy to offer my opinions. For referrence though, I'm a RHBH player, and top out D 430-450' so some discs may react differently to me than you.
First things first though, you gotta get your ratings right. Idk where you got them from, but from my experience and research I find these to be more correct:
Havoc: 13; 6; -2; 3
Flow: 11; 6; -1; 3
Villain: 12; 5; 0; 4
Vision: 7; 6; -3; 1
With someone of your D power, I'd highly back you throwing a Flow, but not as an anny driver. That is unless you get yourself a flatter one. You should most def pick up a Saint (9; 7; -1; 2) great for hyzerflips and holding anny lines better than a Flow.
I recomend either a Trident or a XXX (6; 5; 1; 4) for a short range meathook driver/mid. I lean more towards the Trident (5; 4; 0; +2.5). Its a fantastic headwind/FH/spike hyzer disc. I view those both as a hybrid driver in ball golf.
I see you love your Buzzzes, no argument there, but throw a Core (6; 6; -1; 1) with a lil dome, and you'll shelf those Buzzes within a week. Just saying.
You can see what I throw in my signature. If you have any questions about ofther discs, just PM my or something and I'm happy to help. Just remember these important things about Lat64. While discraft and innova have inconsistentcies with dome/no dome, Lat is very straight forward: dome=bit more OS, flat=bit more US qualities. The only disc this doesn't apply to is the Trident, flatter the better. They are also very form/nose sensitive. If you have bad form, or have had things hidden by other discs, you'll find that Lat's discs will really show those issues with form. The plus molding aids in glide, but many find them easy to have slip out of their hands. But with time and practice, you'll never find discs easier to control, glide for miles and flat out wow ppl on the course with how they look. Enjoy whatever you choose to throw.
