Youre right, the choice of replacement grips is a minefield.
Bear in mind, some weigh heavy, like the Wilson Shock Shield and Pro Hybrid. Others are light, like the thinner grips, Skin Feel and Prince Resi-Thin. The thin ones will feel like a compressed standard grip also.
If you can remember what grip you had on your rackets originally, I would stick with those, otherwise you could affect the balance and feel of your rackets.
