Most of the new materials manufacturers use do work as stated, although may not at the levels of advertizing.
The bigger problem is in the way rec players look for racquets. If you have a racquet for 5+ years and you play frequently, your racquet has gone soft over time and you have become accustomed to the softer feel (especially if the racquets have heavy wear in the frame from scrapes). So, when you go to buy a new racquet, even the same exact model, you feel that the racquets dont feel the same. We see this all the time and show customers by measuring and comparing the flex of the old and new racquets. They had no idea how soft their old racquet had gotten.
The comments about lighter frames are correct and NO Pro plays with a light frame. ALL Pros play with customized frames.
it is interesting though how these technological wonders are especially liked, most of the times, only by rec players. i've talked to competitive players, people that made a living out of tennis, some of them just national, some of them top 100 atp and most of them said that these knew technologies are not so special as advertised.
i especially mentioned the D3O because i know from a tennis player that all 6 of his racquets, the first head racquets that had D3O they all broke at the neck. and i mean the head of the racquet broke and flew across the court.
now considering that people have the tendency to exaggerate these things i am inclined to think that it wasn't all six of them. yet there were others that reported the same problem.
and maybe you do not remember the advertising done by the manufacturer when the D3O was first implemented. the words " the racquet will know what kind of shot you need and get more or less stiff accordingly" were thrown around.
i do not say that these technologies do not exist or do not improve a racquet. but IMO they do too little and they are only a revelation for the rec player.
if one of these technologies was a breakthrough all the manufacturers would have jumped on the wagon. like what happened with multi-layered wood frames, aluminum frames and later graphite frames
