H22 vs Pro Lab Blade

[HolyMountain]

Anyone have any definitive ways to tell the difference between an H22 and a Pro Lab Blade? The only thing I can seem to find for sure is the grommets on the H22 do NOT go all the way to the end of the string channel. Buddy may have accidentally sold me H22 instead of Pro Lab Blades.

"Blade Pro" on top of the handle should be all the info you need

What is an H22 other than mold? No standard H22 really. Depending on whose frame you grab there could be variations in layup, softer, crisper, drill pattern. As far as I can tell variations all over the place. Blade pro just one more variation
