Grafalloy prototype bimatrix, any review out there?


514_type r

Recommended Posts

hi guys, just bought a grafalloy prototype bimatrix shaft and a very high lofted driver (tour edge exotics 12 degree) this is really a try out ro see if i can maximize launch (13-15 degree) while keeping spin in the mid to high 2000 rpm. trying to see if people were able, as stated, to increase their loft on their driver by 2 degree and keep spin very low?

 

any review of the shaft in term of feel and trajectory?

 

I will,on my side, give a full review of the shaft with the 12 degree head . Ill also try to give a comparaison head to head on the vector, with the same driver in 9 degree, with a diamana blue board 63 shaft.

I just put an X flex Bi-matrix in a R5 TP 8.5 head and I really like it. I am a very high ball hitter but am really able to flight this well. I was hitting a bridgestone 469 9.5 with fit on 11 X flex and I think I like the bi-matrix better it dosn't fell as harsh. Averall I am happy with the shaft so far now I just need to get the right weights in the R5.

update about the shaft

 

I did install one in my 12 degree exotics head, and found it very soft for some reason, I was spinning it much more than my diamana, 3200rpm versus 2200rpm with the diamana. I should of gone to an x flex. ball did not baloon on me but did not get a ton of roll out of the combo

 

I ended up installing the diamana in the 12 degree head, it should be a very good combo....so far diamana is the lower spining shaft out there

Would you recommend the graffaloy bimatrix and how much is it?

 

 

I've got a couple of them, but haven't found a head to stick them in yet. If you're looking to buy them, Joe Kwok probably had them. Golfsmith also has them listed.

I found this shaft to feel quite soft as well and launched much higher than I expected. I have it in a Launcher Comp 10.5 and it still hits moon balls. It loads easy, and feels surprisingly smooth for a steel tipped shaft, but it just feels soft. This was odd, because even Grafalloy said it plays a tad stiffer than their other offerings.

try the pink one's they play just a tad stiffer than the black ones...i compared the weights and frequincies on the black and pink in the same flex and the pink came out to be about 6 frequencies higher and about 6 grams heavier...

I've been experimenting with these in some Nike SQs. I currently have an X in an 8.5 SQ Max. It is awesome! My swing speed is around 128 and this thing keeps my spin down to around 2800. That is very low for me, I'm usually in the 3500 to 3700 range. I also have a tour issued SQ Tour with a tippped S (plays like a 1/2 X flex). This combo is good, but launches a bit low, I may need to go with a 9.5 in the tour head. Anyway, I really like the shaft, it does what it claims it will. Of note, the shaft feels like it has more flex then it tests out at, don't know why, just does.
