I just had a driver fitting, the darkspeed max 10.5 and Paradym Ai Smoke MAX D Driver with a 60g blue low spin shaft were my preferred options of the new lineup. Before I dive into spending a lot of money on a brand new driver, are there any models in the past few years that would be a similar spec to these that I could take a look at, of course the shaft is fairly non negotiable so will try and see if i can pick up one of those but wondering what head is similar to those two models?
