Hey guys! Well I'm planning on buying a racket online. I don't know which one to buy though. I'm choosing between a yonex armortec 250 or a yonex armortec 30. I've tried out an armortec before and I really liked how it felt so I decided to buy one. I'm a beginner so I don't really want to buy a really expensive racket. And if I were to buy either of those, what tension should the strings be? I have no idea. If it helps, I'm going to be playing doubles, but I would be at the back. Thanks in advance.
