I can relate. First page of comments were insightful.
Lemme see if I can get us back on track.
@ 3.5 I was about equal at singles and doubles.
@ 4.0, there's a clear edge to my doubles play (mostly because I think I'm good at net play & partner strategy)
But I'll admit to not having played USTA in a few years.
Could I go back (if bumped down) to being a strong singles players, 5+ years later and now over the half-century mark? Not sure, but I'd like my and my team's chances. I like S&V and can still catch some 3.5 ladies asleep at the wheel (I get to play them occasionally in a non-USTA league). That style of play also serves me
well at the 4.0 level, but only in doubles. The 4.0 singles ladies, regardless of their age, are wiser/more skilled to my ways and it's a battle I usually lose. In my younger days, I had stamina (S&V requires more than you think and staying back, without a big stroke weapon, required footwork and perseverance which, admittedly has declined with age). Now, not so much.
A few years ago, I had been looking forward to aging into 'seniors' @50. But with the age now dropped to 40, almost every captain I spoke with wanted me to exclusively play singles. And while I'm a good 4.0 doubles player, I'm not a great one, not one good enough to insist on mostly playing doubles. Nor is that my style. I'm a team player above all else and, having made a commitment to a captain/team, I know I'd do what was asked of me. And while I've never shied away from being the team's sacrificial lamb, I don't want to do it every week. If we
had to play in order of strength, I might consider it but with stacking more than permissible, no, thank you.
