wat u mean by no solid feel?
is it the racket too much vibration?
or cannot feel the sweetspot?

oic...
may i know...

wat is ur racket head size?
wat string and wat tension u use?
wat is ur racket weight?
wat is ur racket head balance?
do u always brush up on the ball (topspin) in ur strokes?
do u feel vibration in ur racket when u hit? and do u use a dampener?

oic... i think the ting ting sound usually its bcuz of the string... sometimes the racket also may cause this kind of sound, and therefore have to use a bigger dampener

u can try using a synthetic string with the same tension and see whether its better for u or not
another thing u can try if u dun wan 2 change ur string yet is to put a longer/bigger dampener (since u are already using one but i suppose u are using a small wan), or use a thick rubberband

if u brush up alot in ur strokes, u can try swinging more forward movement instead of just swinging upwards alone, to get more 'pop' sound. but be careful though, bcuz since u are using a large frame and light racket, u need to topspin alot. ur ball may go long if u swing too much forward... so try to swing forward but dont compromise ur brush up (topspin) movement

hope this helps
