"Only the putter can be hooded to any advantage" (I forget the chapter)

It works very well for learning to hear the 'click' of a solid impact with the putter. I think it almost can work too well if that is possible, to the extent that when you try it you may find that the better impact makes distance control/power shift and require less 'effort' for a given distance. The downside is a ball that hops, which indicates too little loft and/or too steep an impact.

I notice a similar effect from C-grooves and a hooded putter.

What is your opinion on the c-groove putter by Yes Golf with lofts of 2.5, or 3 degrees? Do the C grooves have the effect of increasing the effective loft? Thanks for your reply.
