Another view of the same. Fast to slow, overstable to understable.
@cjk7689 Mockingbird is more understable than Grace. Easy flip to flat, or release flat to drift right. I'll throw the Mockingbird out to 320 or so on backhand—I don't typically throw it forehand.
Grace is the quintessential stable distance driver. Just a small turn and then hold the line. I'll throw the Grace FH to 320 or so, and BH to 360 or further.
I'd compare the Mockingbird to the Leopard3. But I really like Lone Star's Alpha plastic. It reminds me of older Latitude 64 Gold Line.
