Considering using a hybrid string setup. Have Luxilon Big Banger Power Rough-16L and Gamma Synthetic Gut 16. I think Federer uses the Luxilon on the crosses and natural gut on mains. Would that setup give more topspin and feel using Luxilon Power Rough for the crosses? Durability is not an issue for me as I do not break strings. Plability is more important.
