A GOOD fitter will put you in a combo set off 100's/150's. I was in the same boat a few years ago, still around scratch (been there 30 years), thinking highly of myself. It was an easy decision for me based on the flight characteristics. In the windy south, the high trajectory MB/CB's were getting tough to hit consistently, for me. The new ProV1's spin so well off the irons I was getting crazy height at the peak. Everyone is different though. There's a reason most of the Tour guys have given up the conventional blades, and it's about forgiveness. It's a tough call to make, based on your ability, but a good fitter with Trackman will show you the evidence. Good Luck!

Honestly I was in the same boat and the staffer fit me into 620mbs 9-6 with T100 in the 5 and 4. I use an sm10 46 for my pitching and absolutely love the setup. I recommend it ! Might really need to adjust lofts but besides that it was an easy setup to start playing with. I do agree though that it really depends. Try to find a fitter outside on a grass range. Turf interactions are crucial when getting fit. That’s the only reason why mine recommended me into the 620mb’s cause of my swing and spin they fit best for me.
