    Head Velocity

    Hey @BlackMagic I haven’t read this whole thread ... can you summarize for us? LOL ... basically the idea I get is it’s the best string before needing to go poly if you’re not breaking strings. Most popular as a cross substitution for smooth poly if you don’t need durability. holds tension...

    Head Velocity

    I was curious what velocity's measurements were at other tensions/speeds/ diameters and decided to run a machine learning model that learns all the TWU data and then comes up with an estimate. So far I've only used it on the "stiffness" rating but could be expanded to other measurements. I'm...

    Wilson Ultra Tour stringing instructions

    Hi Irvin, yea I'm kind of tentative on enlarging the grommets too. But grommets are cheaper to replace than busted gut strings ...

    Wilson Ultra Tour stringing instructions

    Does anyone tie off the starting cross to a cross instead of main at 6TOP when using hybrid? I'm not a stringer but am curious how this is done with this model.

    TWU String Performance Database - Changing Values?

    FYI, string data does sometimes change depending on how you filter your searches. For example with head velocity 17 if you search only the string you will get 0 values for stretch @ 40 , 51, 62 lbs Do the search again with all strings and you get some numbers that don't make much sense (stretch...

    2020 Prostaff update

    I hit with a v11 today 4 1/4, it was the smallest 4 1/4 I ever felt. Even had an overgrip. and seem like the black was chipping away. Are prostaff handles different from other wilson racquets and run slightly smaller?

    Head Velocity

    Depending on how you filter/ use the search in the TWU string database velocity's stretch measurements are either N/A or @40: 1.8% @51: 8.5% @62: 6.4% or @40: 2.1 @51: 5.8 @62: 8.5 I've seen it one time @40 : 2.X @51 : 4.5 @60: 4.5 How the hell does that happen ??? Are there any other...

    Today was the first time I played with no wrist pain in a month!!!

    I was considering getting a radical tour OS to play with during this injury period. The specs are fairly close to your current racquet right now i think.

    Today was the first time I played with no wrist pain in a month!!!

    Yea it felt like I was hitting a ping pong ball lol. We would need to be able to swing a racquet that's almost twice as heavy to feel like we're hitting an orange dot. Funny enough there was a time when 8oz super light racquets were peddled to consumers, i did hit with it once and every ball...

    Let's Gather All Grip Specs (Weight & Thickness) into two threads

    This depends on the material - synthetic replacement grips usually have a less dense foam layer that compacts the most. thicker ones usually have more foam. - overgrips are usually made out of some polyurethane similar to the outer layer of a replacement grip and compacts less. 2.1mm...
