Update:
Grips and vibrational inserts are a success; Grips feel great (I played them without a glove) and the inserts do make a difference on the sting one gets on mishits in the winter cold.
I am a bit mitigated towards MIO matching : I appreciate the slighter heavier feel on the wedges and short irons, mid irons stay the same of course and long irons I could get used to quit easely. The very low SW driver however was a struggle of me trying to addapt to the club instead of the club being adapted to me. I'm definetly not going to go full monty on MOI. I'll finish the MOI set and put them in the bag for a couple of rounds, but leaving my woods as it is.
