Deciding between these four rackets
I'm sorry for what's probably the 4 millionth one of these threads, but my budget is thin and I'm not in a place where I can demo rackets.
I'm a 41/M and a beginner trending towards intermediate. 5'9 190lbs and relatively strong (though not especially so). Play maybe once a week. I'd like to find a racket that will be easy on my joints, because my form is probably not the best yet and I really want to avoid injury. I know these have stiffness ratings, but my understanding is that doesn't tell the whole story. Would probably put some 55PSI strings on. Any insight at all is appreciated.
