Tibhar rapid carbon light, balsa core, koto outers. Original rapid carbon had smaller head and quite comfortable handle, not sure about light versions head size.
But still change in technique would eliminate wrist problems eaven if there were some seroius ones. Mri showed nothing so its nothing...
Here is a radical idea, dont use wrist for a good while, get yourself some sort of wrist wrap and just play. It will be good for your technique and will force you to correct it.
Your problems might be equipment related, if your racket is too slow your technique suffers and than these things that you described happen....
You might try training a bit more ( 2 sesions 15min each ) and if you STILL have same problem its definetly equipment related.
Try getting a Schlager...
Sorry for Croatian guys:
Vidi kod Pelina ima super Xiom premade rekete koji imaju odlična drva i gume a gume se daju skinuti pa se na drvo opet može ljepiti. Mislim da je u tom cjenovnom rangu to. To ti je definitvno naj naj šta se da iskombinirati.
Yes, any thicher 5ply blade with softer top ply like limba, Butterfly Peter Korbel comes in mind 1st. Also doesent have to be thick if it has hard medial plys like Tibhar Samsonov Alpha for example.
There are S1 & C1 in 45 degree hardness but never tried any of those, those might be too big of a jump in hardness since FX-P is 39-41. Baracuda in 2.0 might be perfect, much more durable, not as bouncy and just a bit harder.
