are there any opinions from folks who have the limb shift tech on whether using it to adjust instead of shimming results in a loss of speed when compared to shimming? Just seems that the true "right way" to accomplish center shot is putting the cams where they're perfect as opposed to basically slanting the limb. I have a v3x and shimmed it..not a big deal if you have a press...so I'm trying to figure out if the limb shift is simply a feel good for folks who may not understand or have a press to actually shim for centershot.
