I think Polaried rackets (rackets with a higher Recoil Weight) has been blown out of proportion. A uniform stick with have an inertia around the center of mass equal to 1/12 the mass times the length squared. for instance if I took a stick 68.58 cm long that weighed 325 g or .325 Kg it would have an inertia of .325*68.58*68.58/12 or 127.3787775 Kgcm^2 around the center of mass which would be located in the center of the stick at 34.28 cm. If I wanted to calculate the inertia 10 cm from one end the it would be equal to the inertia at the center of mass plus the mass times the distance from the COM minus 10 cm squared or 127.3787775+(24.28*24.28*.325) or 318.9722575. Now that is not bad if you have a racket with a SW of 319 and total weight of 325 it that is what you want. But that uniform racket would have a high balance of 34.28 which may not be what you want. If you want to change the SW, TW, balance or total weight then IMO it would be best to address that and not RW, unless of course you're going to swing the racket around the center of mass.
