Hi, thinking of most popular Prestige versions (microgel/youtek) i wonder: MP version is definetly the most popular - i can name at least 10 or more pros from ATP top 100 who use it. PRO - only Wawrinka? So my question is why do you think all use MP? MP: 18x20 pattern + 63 siffness PRO: 16x19 pattern + 66 siffness As we see above differneces aren't huge.. P.S. Anybody saw MID version in ATP?
