Recently bought a new stick (Head Graphene Instinct MP) with Topspin Cyber Flash 1.25 strung at 57/55 lbs (26/25 kg). Now my old setup was a Head YouTek Speed Elite with Luxilon Alu Power Rough strung at 55/55 lbs (25/25 kg), so the strings/tension were pretty similar. Now my problem is that my balls fly mostly long all the time and it's kinda ruined my game. When I was testing the new racket it was strung hybrid with a poly in the mains and some synthetic gut-string in the crosses at 62/60 lbs (28/27). It felt great, I was comfortable with it, so I bought the stick. Now what should be my next move so that I get more control back? Keep the polys and go higher in the tension (how much more would you recommend)? I read that polys shouldn't be strung too tight, is that right? How drastic is the change from full bed poly to poly/syn. gut hybrid? Sorry for all the question, as you can see I'm not really an expert on these matters, so any help would be appreciated.
