MG Tour C4 - $20/dz online - only have in white so far.
best poor man’s proV, for the money, I have played. I love Maxfli Tour as well, but is a little more expensive.
Did you have your lofts weakened? Based on Callaway, Apex 21 standard lofts are below. This could also explain your increase in distance...but I don't know what "Wunder Spec" means either.

Many have been saying using armlock should be illegal because the locking prevents face rotation.
The last time I checked, my forearms (radius and ulna) can rotate freely from the elbow with or without a putter attached.
