I have a Head Microgel Instinct. I just started playing tennis last summer. I try to play 2-5 times per week. I have a flat serve try to come to the net off of bog serves find I play baseline a majority of the time My primary shot is na heavy topspin, high, deep reverse forehand I have a weak backhand, and cannot hit a slice I want to know what strings would be best for me. I read that natural gut is the gold standard. I do deal with elbow pain at times (I swing like a mad-man). I want a string that allows me to continue heavy topspin, comfortable, and lasts a fair amount of time. I know this is probably too broad, but any help would be great.
