Given the very open 16/15 string pattern of both the Wilson Steam 99S and 105S, which string would you choose for these spin-friendly racquets? Wilson recommends the Luxilon 4G for maximum spin and the 4G S for durability. However, these Luxilon strings are not the most inexpensive ones, which may be an issue considering the expected short lifespan of any string in the new Wilson Steam S-line. So what are your ideas for the Wilsons? It may be tempting to use a lively, spin-friendly string to furher increase the already huge spin potential of the racquets. In contrast, to prevent breaking strings to early it is probably wise to choose a more solid string with a thicker gauge. My first idea is to try a string like the MSV Focus Hex 1.27. That one gives you a lot of extra spin (see the comparison tool on tw), yet the relative thickness may lift durability to a sizeable level in the new Wilsons. Also, the MSV is affordable, which may be big plus. So, what are your thoughts? Any proposals?
