Hello...I am looking for a ball to in the Roto Grip line that will go a bit longer and have more backend than the Sonic X Solid. This is for a family member who has 13-14 mph speed with low-med rev rate. The pattern is a THS maybe a touch on the lighter oil side of things. Any help would be greatly appreciated. Thank you.
