Jerry,
With all due respect to the superintendent, I think it's the other way around. Most players can't spin the shots that you are talking about no matter what the grass is; it's the better players who CAN spin the ball that have to change some of their shots. For most of us, bermuda greens hold just fine because we're used to seeing our pitch shots roll out anyway. Better players don't like the changeover in many cases because grain makes it MUCH harder to execute the hop-and-stop pitch from off the green with predictable results; sometimes the ball stops quickly, and sometimes it doesn't. I think clubs that are either contemplating the change or have made the change typically get more push-back from the better players, not the lesser ones.
By far, I think the bigger issue in the changeover is the question of whether or not the greens need to be recontoured to account for typically higher green speeds and more grain. I've seen places lose pin positions, in some cases dramatically so, by not recontouring. The Farm in Dalton, GA used to have a pin sheet map with 6 positions when they had bent grass greens; they now have a pin sheet with 4 positions with Champion Bermuda greens that run at 12 on a daily basis. That's an extreme example, but you get the idea.
The supers on the site might disagree with me, but I think many supers that have spent their career with bent grass greens are just not particularly interested in the paradigm shift involved in a conversion to bermuda. It isn't that it's more or less work; it's that they have to relearn the magic tricks that supers are required to do to keep greens great year-round. All of us do that in the workplace after a long period of time executing our job successfully. The super that you mention may be pointing to something else rather than saying what is really going on. Just my opinion...
