I don't have personal experience with the Dyno-Thanes nor rebadged as 3G but I've heard great things about them. I have a pair of SST7s that the push off shoe is coming apart on so I would stay away from those, the SST7 SEs are better made though.
I'm not familiar with Dyno-Thanes, but I have the SST7 SE's and really like them. They required no break-in time; very comfortable and a great fit, highly recommended. I believe that
Dexter has now released the SST8 model, but I haven't seen them as yet.
I noticed that Walter Ray Williams Jr. was wearing SST7 SE's at the recent Men's World Championship Bowling Tournament held in Thailand.
