max400i L4 364g 31.2cm
max400i SL3 350g 32.5cm
max400ipro SL3 346g 32.3cm

So, not surprisingly the L4 is much heavier and much more headlight (we already knew this would be the case though).

The others are more interesting though, and it looks like you are correct YonexRX32, as the "pro" version is slightly lighter in weight, but slightly more head light!

With normal standard IMF rackets the weighting (SL, L, LM, M) is all done in the grip as far as I can see, and also the bigger grip sizes are heavier (and more head light) than the smaller ones.

But with the "pro" versions, which are slightly less heavy, surely some weight has been removed from the main part of the racket, does that make sense? I'm guessing by using a slightly different internal mold of the racket. So when the grips are attached, these "pro" versions will be more head light than their non-pro equivalents?
Jimbo,
Thanks for posting the info! The reasons could be multiple for difference between the pro's and the regular. It could be that the mold is slightly different and the thickness of the wall is different, could be that the % graphite and type of graphite used is different. To know for sure we could cut a section through your pro and non-pro 400i.
