Hello, I have hit with the original head ytk speed mp 18x20 for a while now. I am possibly looking to try out some other racquets but I am really happy with my head speed. Based on specs it seems like the head ytk prestige mp is very similar to the head speed mp 18x20. Does anyone have any comments about the difference in feel between the two racquets? Also how similar is the head speed IG to the head speed? I heard there were some issues with stability and mass in the new head speed IG model. Thanks, Ryan.
