Another swingweight question

[Deleted member 25923]

Say I have two racquets:

A KPS88 with a swingweight of 345

A TF Tfeel 305 xl w/ a swingweight of 350

The TF racquet has a higher swingweight, but much less static weight.


So, in a way, swingweight may be irrelevant in certain cases about how demanding a racquet is. I mean, i'm still swinging a near 13 oz racquet w/ the KPS 88 even though the SW is less.

I guess the same could be made for the threads about maneuverability. I'm still swinging an 80 lb couch!

Here's a similar scenario:

I have a KPS88 with a SW of 330 (shaved bumper), static weight is somewhere around 13.1 oz.

I also have an i.Prestige XL MP with a SW of 345 and a static weight of around 12.6 oz.

To me, it's easier to play with the i.Prestige XL than the KPS88 even though the SW is 15 pts. HIGHER!! It's more maneuverable at the net and "easier" to swing than the KPS88.

Remember that the SW is a mathematical number representing the moment of inertia based on a fixed axis. In the real world, it can be misleading.

^^^ I completely agree. It is based on a fixed point of axis - the bottom of the handle. But if you swing with a straight arm, you arm adds probably about or more the length of the racquet. Swing weight is really only accurate for someone who does not swing their arm but simply moves their wrist back and forth.

I may be wrong, but if i am right then a heavy racquet with a low sw may be harder to swing than a light racquet with a higher sw.

This is very interesting! I've been wondering about this! I always thought swingweight is more important than static weight but after switching to a lower swingweight and higher static weight racquet, it didn't feel that much easier to swing. Reason for the switch was because I was getting tired by the end of 2nd set in matches but didn't work out the way I expected.

old racquet: 340g 338 swingweight
new racquet: 348g 328 swingweight

yea I've thought about this for awhile as well. no way an 11oz strung racquet with a sw of mid 340s (case in point, new head youtek radical) is more demanding than say a K90 at 12.8oz with a lower sw of 338. I think sw only becomes a factor in determining how demanding a racquet is when the static weight is above a certain (though not arbitrary) point.

Cool. Thanks guys.
