Moni_SLO I had a similar experience at Club Champion. My wife got me a full bag fitting last year. I went in thinking my irons were ok, but driver was $h*t. We started with the irons and was able to find a better fit. We moved to the driver and nothing made a major difference. He ultimately told me he could sell me a driver that would get a little bit more distance but my swing was so inconsistent it probably wasn't worth it. He did adjust my current driver some to help.
I ultimately did buy the irons through them, and they just ordered the full clubs with the appropriate shafts and grips from Mizuno and ensured the specs were correct when they came in. So they were willing to save the money as opposed to buying them all separately.
Club Champion seems to get hated on a lot across different boards, but I've been pleased with my experiences.
