Occasional Tour Caddy
Name and club to back up cat 1 for 40. Years status claim? Look at the comments from other low handicappers most agree it's much easier for high handicappers. It's fact. There is no way if you had all this experience you wouldn't be able to see this. How many yards are knocked off your course in winter? Maybe you have never experienced this and so have no knowledge. Our course has large revines with tight tee shots through trees but in winter these are missed out, takes all the danger from hole and shortens them massively so accuracy and distance no longer important just comes down to a chip and putt. Still a few holes that we don't mind giving shots. Birdies are not particularly easier in winter, yes you get closer but putting on winter greens is bobbly and ball doesn't hold its line but pars are easier as greens slower and so much easier for lag putts with a shot.
Late to the discussion on this topic but it does sound like you have a course where the primary/sole defense is these long/tight carries from the tees (bit like Augusta & their greens) and combined with your Cat 3&4 membership having deadly short games, (which also makes sense in that the higher h/cap guys are simply using their shots up the rest of the year on these carries/tight tees, and they'd probably clean up when playing a more 'normal' course layout) then yeah I'd say you're gonna get pummeled a fair bit in a winter match
Maybe one for your AGM but artificial ground cover on these teeing areas would seem to offer a solution to keep the length up so no need to protect them in winter, because I don't see too many other courses having to cope with this 'perfect storm' scenario that you face, so its unlikely they will be any widespread call to change the 90%
Might seem an extreme measure but if the design off the tee is that integral & critical to the play-ability of the course it might be worth considering
