I normally use hyper g soft or yonex poly tour pro 1.20 main with head velocity 1.30 cross. It last me about 8 hours till cross break. I tried few reverse set up a few weeks ago, all velocity main break between 2~4 hours (with yonex ptp cross only). So I just wonder if I put velocity full bed, how long it will last for me? I know i should try myself, but i couldn't do it for the next few weeks. Thanks for any info you know.
