We have a small "pro shop" in our club that pimps the latest Babolats, Heads, and Wilsons. Even within those lines, they never carry any of the softer, smaller-headed, or heavier "player" sticks like the Ultra Tour, RF, Pure Aero Tour, etc. It's mostly the "lite" and "spin" versions. And the pros at the club are in on it via sponsorship: most players ask what their favorite club pro thinks they should play, and they end up with a light, stiff game-improvement stick like a Pure Drive Lite or Ultra 103S. It's especially sad to see this happen to so many talented but non-gearheaded 4.0s and 4.5s or upcoming strong juniors. It's so sad to see these players never even exposed to players' racquets or quality offerings from other brands like Yonex, Volkl, or Prince. Is there any way to shake up the monopoly?
a surgeon is gonna find something to operate on
a mechanic is gonna find something wrong with your car
a car sales is gonna want to sell you a car (who cares if you already have 3 you can't afford)
a doctor is gonna prescribe whatever drugs his hospital/practice gets a kickback from (why don't they ever prescribe generics, first?)
a tennis pro shop is gonna want to sell you a new racquet
a non-gearheaded tennis player (or anyone not very knowledgeable), deserves to get upsold
that said, a service-based-sales person will guide you in the right direction, regardless of whether they make a sale or not, but we, as the consumer, need to pay that consultation fee... but instead, like most folks, we're too cheap to pay for good advice (granted, the definition of "good" is debatable, it's not like there's a racquet-recommending-certification).
IMO, find a good pro, preferably someone who has a resume (d1, atp, popular published expert, etc...), and ask their opinion during the lesson. they probably can't recommend a specific (modern) racquet (they might even say buy a 1990's racquet!), but they can educate you on the qualities to look for, and then you can ask more intelligent questions to the tennis pro shop sales person (ie. i want 5pts head light, ~12oz+, stiff/soft frame, etc... )
