Dear Sirs,

Can you please tell me what the specifications would become for a Youtek Speed MP 18x20 if 5g was placed on the outside of the hoop at 12oclock by means of 5 layers of 2inch per layer of weight. I understand there is a 'fill in the worksheet and it will tell you the result of your mods' page but its too complicated for my simple brain..

In stock form, the strung weight is 335g the swingweight is 317g, the stiffness is 65, the balance point printed on racket 310mm and after stringing the TW balance score is 7 pt HL.

After the above modification can you please fill in the following 5 blanks. (The first one has been done since it was the only easy one) Thanks:

New Weight: 335+5 = 340
New Swingweight =
Stiffness (if it would it change) =
Balance Point = (Basically if it was manufactured like this with 5g at 12, what would be printed inside the throat instead of 310mm assuming an unstrung state)
TW Balance Points= (as are measured for strung racquets)

Sorry for anyone who is offended by this wierd post and sincere thanks to anyone who can actually calculate and provide accurate answers for the above.
Thanks.

Using the TW specs and the customization worksheet the new specs of your YT Speed MP 18x20, assuming you add 5 grams of lead at 12, would be:

New Weight: 340
New Swingweight = 334.2
Stiffness (if it would it change) = should not change
Balance Point = (Basically if it was manufactured like this with 5g at 12, what would be printed inside the throat instead of 310mm assuming an unstrung state) -- no idea as I used the strung balance
TW Balance Points= 5.4 pts HL
