As you can tell by my sig, I'm definitely a mixed bag guy. Personally I think it would be hard for someone to fit me with the same OEM from driver to balls.
I'm single set in my irons, but I wouldn't be against a mixed set if it worked better for me. I have Cleveland wedges in the bag right now because they were less $$, but I've loved my Callaway wedges and would play MD4s if I found them at the same price.
Mixed bag right now and have been single OEM in the past. Several OEMs make clubs top to bottom that will work for me so if I decided to go back that route I can no doubt put together a bag that works
I like having a mixed bag of OEMs. It frees me up to upgrading any piece of my setup at any given time to whatever works (or looks) the best for me at any point in time. No waiting for the next release if the current release from any particular OEM isn’t in my wheelhouse.
With so many companies making good clubs that will benefit a wide varierty of golfers id be silly to not play a mixed bag otherwise id be cheating myself
I hope we all understand the pros aren't playing off the rack equipment. At a minimum, they are getting a fitting like most of us have never experienced. At times pros have been known to use another company's equipment and modifying it for their use, including putting their sponsor's logo on it. More commonly, you see players sporting 'prototypes' with their sponsor's name. Many of these prototypes never see the light of day, other than these player's bags.
Like most of you, I neither have someone available to do what is available to these pros nor do I have those skills to do so myself. So I get fit with a brand agnostic view. I let the numbers speak for themselves. That approach NEVER leads to a bag with all the same brand--much less off the rack configurations.
