So, its sounds like if you are a strong topspin hitter and you also want to soften the bed for comfort and touch then polys (probably smooth is better) in main and multis in crosses is a good combination. The problem is that it will not take long for the multis to fray and break, usually within 5 days of use. What multi would you recommend to increase its durability in type of hybrid combo. X one biphase, wilson sensation, prince primer attack, head RIP control which one of these would you suspect to hold up the best (all 16G)
