    because for the reason i gave above, it's heavier

    How much heavier exactly? Have you put them on a scale?? I was told by my Yonex rep here that the weight (given the same speed of shuttle) should be equal regardless of model, but I have not measured myself as I think both shuttles are stinkers

    Yes, I am biased (aren't we all more or less?), but always open to new knowledge, and facts

    And I did not take the Yonex rep word as is, thats why I was asking you if you had any solid figures on weights... Which maybe even could be interesting given the original posters question in the thread :-)

    I just opened 1 tube of M300 and 1 M500, Sorry, I do not have M350 at this time.
    avg of 2xM300 = 5.05g
    avg of 2xM500 = 5.10g
    Please note that the skirt of M300 and M500 are different.
    I might get a M350 this weekend to do some measurement and see the BP also. I will not do flight test because my swing might not be consistent.

    Nice , Cooler-Yonex 1-0

    (and btw thx for the effort, & info :-) )

    Did you weigh them separately and averaged? any deviance between individual ones?

    /T

    P.S. it could be interesting to compare this to the weight of international-tournament-shuttles (feather). where 5.0 gram would be a speed 77 shuttle, and 5.1 gram would be speed 78. so that would mean 5.05 would be 77 1/2 ... D.S.

    Dear T,
    The shuttles are weighted separately then average. Deviation is 0.1g for M300. 0.0g for M500. I will try to get a tube of M350 and weight all 6 shuttles in each 3 model this weekend.
    Dear Cooler,
    They are med speed. You know me and you already knew the answer. Thank you for the reminder.
    I love scientific investigation... Good night gentlemen.

    How come the Greatest GrandMaster SH is doing all the work? What/where is the other great scientific mind doing?

    Not bad, u knew i knew
    ya, i have the 4.85g number stored in my head so 5.0g range is med. speed

    Shutter speed designation used to come in 48, 49, 50, 51, 52, etc to denote its weight 0f 4.8g, 4.9g, 5.0g, etc. This was not a very accurate classification so the current speed classification of 75, 76, 77, 78, etc is preferred. This system uses a 30cm distance difference between one grade and the next speed grade. Surprisingly this system was in use many years ago, even by nylon shuttles which used to come in speed grades of 76, 77, etc. Both the weight and the diameter of the feathers shuttlecock are the major factors in shuttle speed.

    it seem mavis 350 (and 370) generally weigh more than mavis 300. This support my experience that mavis 350/370 flies faster than mavis 300 of the same SLOW speed grade, and why mavis 300 is more commonly used than mavis 350/370 beside price factor.
    So according to cooler 350 is heavier than 300, and 500 is heavier than 350.. But the measuers from SH seems to contradict that as 500 seems only slighter heavier than 300.. So how could it be heavier than 350? Or is this just incosistensys because of these shuttles being so cheap

    How about testing Mavis 300, 350, 370, and 500 for speed on the courts? Do they land within a distance range of 46cm, measured from a point 53cm from the back boundary line towards the front?

    That "test" seems kind of silly, as conditions like humidity, temperature, sea-level etc. will affect the result :-), Thats why they are made in different speeds in the first place , so in essence at one venue a "medium" 350 may have the correct speed, on another it will not...

    If any of the 3 speeds available are not good for the venue, there is no solution to adjusting the speed permanently on these plastic shuttle .

    Don't worry, the feather debate was started by taneepak when he was pushing feathers in a mavis 300 vs 350 thread.

    the 500 feels heavier than mavis 300/350/370, and yes slightly more durable too. The 500 is not commonly used. Better stick to 300 and 350 because most nylon clubs and school use these 2 types. If u played with 500, u could be at a slight disadvantage if u r planning to play with other nylon players. Personally i prefer 300 because i can adjust the speed to suit my area.

    can tell that you are familiar with plastic shuttle.

    hm....
    SH weighted the medium speed (blue)
    cooler weighted the slow speed (green)
    will it be difference?
