Since we have 8 racquets among the 4 tennis players in our family we’ve decided to get a home stringer. I think we’ve narrowed it down to the Apex Speed and the 350-CS. It looks like the Apex Speed replaced the Apex II which has been well reviewed. However, I haven’t been able to find any reviews of the Apex Speed. Looks like the 350-CS is well reviewed as well but a couple hundred dollars more than the Apex Speed. Anyone have any experience with the Apex Speed and how it compares to the 350-CS? Thanks!
