Hi there. I am using a 910D with a diamana Ilima 61 mid-hi flex-S which I have used for about 2.5 seasons Which seems to suit me pretty well but always looking for something better so I have recently bought a M2 drive with a speedrulz A-TYPE 50R which unfortunately doesn't seem to work for me I tend to leak it to the right consistently so thought I'd try a diamana s60 stiff in the M2 Head Again struggle to keep it to the centre of fairway or the left side always leaking it to the right So probably not the shaft for me So I was thinking of trying the new Titleist driver when it comes out or the 915D so just some advice on the right shaft you think will be good for me knowing the Iliam shaft is working very good for me. Thanks. Carl Dean.
