Any thought on the new Dunlop bio m3.0?

[JAT]

How is the m3.0 compare to the old bio 300?

[LeeD]

Looking at specs, a slightly wider top of the head, a slightly firmer feel, has 10 points more swingweight, for less manueverability and more plowthrough.

It was very disappointing. Very tinny and pingy feeling. Feels like he frame is made out of balsa wood.

[LeeD]

Sorta agree, the demo I tried felt tinny and light, sweetspot small, but it was a F3T.
My Bio300T would feel like that, if I strung at 58 lbs.
Lucky for me, I spec'ed 52 from TW here, and it's solid with 12" of lead at 12-2.
My bud's Bio300T feels like a toy POS, but he's a slicer dicer and likes the firm feel.
Strung softer at 47 or so, and hitting through the ball with a FAST long stroke, these rackets must feel like a hot blade slicing thru butter.

Would't play this stock but with leather grip and 6gm lead total in hoop:

great control
great spin for 18m
best plow through-to-weight ratio
quite forgiving on off center and defensive shots
more powerful than 4d-300 but very controllable power with even response
one of the best serving racquets I've used
better overall, including feel, than my previous blade 2013-18x20

I've now switched to clay for the summer and changed to full poly string setup @45/43.

Thanks for the input. It seems the sweetspot is smaller than the previous version. I wish I can demo it in Australia.

Sweetspot size totally depends on grip size and string tension.
Most U guys want to use 3/8 grips, and 58+ string tension. That shrinks the size of the sweetspot.
When Fed and Nadal use small grips, they counter with bigger swings and heavier rackets....and a dose of added skill. Yet they string around 50 lbs.

Hi Lee,
Could you please explain to me why if you reduce the grip size can increase the sweetspot area?
I thought if you use smaller grip size than what you suppose to use can cause tennis elbow?

Try holding a pencil sized racket handle. It will twist in your hand on any kind of off center hit.
Now try holding the barrel end of a baseball bat. You never feel twisting at all.
What is our definition of "small sweetspot"? It means the ball hit off center really twists in the hand.

Hi LeeD, cheers for the explanation in that case if you use a bigger grip it should increase the stability and should not twist in the hand.

It increases non twist until you notice a certain lack of fluidity and movement of the wrist, on some groundies and most serves.
I'm 5'11" and 150 lbs, very thin build. I use a 4 5/8th size handle. Possibly because I"m old school, possibly because I play net more than half the points, and possibly because I'm stubborn and pigheaded.
I find smaller grips like 1/2's with overgrip are easier to switch grips, faster to, but serve the same and have more wrist power, which can lead to inconsistencies.
I don't need more power. I need control and repeatibility. My power is adaquate up to 5.0 doubles, but my control is no where near.

According to Dunlop 2013 tennis catalogue “The fully re-engineered frame shape of the 3.0 range features a 15% rounder more eliptical head shape than the previous 300 model to enlarge the sweet spot of the racket.”
I guess this is just a marketing hype.
Lucky I haven’t order the m3.0

Can you read post #2 again?
There is already a post on this subject, and one of the 4.5 level TW posters wholeheartedly endorses the F3T over the Bio300T, saying the wider top of the hoop and heavier SW are contributing factors.
