I use a max weight eclipse reactor for my OS mid. Great for flex shots.Have 3.
Eclipse is very flat but very overstable. Close to max weight.
Blank Neutron 174 is more OS than a new Buzzz.
Stock stamp 169 Neutron is more biddable. Not enough throws to render a full verdict, but this one is the closest to what I'd hoped for.
I really like the feel and speed of this mold, it's the best MVP mid yet, imo. Really interested to try a Hex and compare/contrast the two.
