Can anyone recommend their best choice of rugby upper body protection?

I started playing this season, and used a basic Rugbytech shoulder and arm protection, and have thus far managed to mess up my rotator cuff and my ribs under the right pectoral. I know, my body will get used to the contact, but in the mean time I'm spending way too much time injured and not getting the training and game time I need to progress. At present, with messed up ribs and shoulder, I'm flinching out of tackles in anticipation of making things worse,rather than hitting hard like I used to, Any recommendations are appreciated! Thanks
