Hi I am new to this, so i am 64 years old been playing at a reasonable club standard for 50 years! So I have many rackets more than i Know what to with! So I bought the React 295g 18x19 last year when it was released, I also got the TC99 18x19 last week 300g both are strung with the same string at the same tension Angell comfort hybrid. The React has some lead 2g, the TC99 is stock weight. First impressions of the TC99 is that it has greater plough felt slight more stable & comfortable than the react! The React is crisper, comfortable if hit in the centre, however off centre the TC99 was more comfort. Power wise the TC was more powerful and felt more solid. It is slightly more muted which to be honest having had opps on my elbow and Shoulder it better for me! React gives more feedback but as I have eluded feels less comfortable than the TC. I also have a TC100 & TC97 18x20 octane! I would say that the TC 99 is more manoeuvrable then both More control than the TC100 less power lower launch angle, but more powerful than the TC97 & slightly higher launch angle i.e in between the TC100 & TC 97. Initially when i Bought the react, i had been playing with Prokennex Ki5 295 (with a little lead on tip) Same tension different strings. I bought the React out of curiosity, whilst i played well with it, I felt less comfortable than my Ki5s, I also found them slightly less powerful whilst control were similar Ki5 16x20 very dense string pattern in the middle! I have had one outing with the TC99 18x19 I have to say i like it better than the React, more powerful more muted and stable however less manoeuvrable (slightly) Got to say though cosmetic wise React looks nicer!
