I used the 17G and read this one is softer, very true feeling when hitting the ball, not too much power, bu good control and feel during stroke with great spinning action.
Remind me of the RPM Blast. Strung my Head Graphene XT Radical Pro at 54lbs and these are absolutely brilliant. Great control and spin. Bit muted on the power but I can generate my own so it doesn't matter. Overall great value!
