Over 65 here on OS rackets.
4 or 5 yrs ago a former SEC player now college coach called me a sandbagging 4.5, I don't know about that. I just play a lot of tennis with high school kids, occasionally a college player, guys my age who have been playing 50+ yrs and everything in between. I get a kick out of hitting tennis balls. My eyesight has never been stellar. And I have some bad habits I picked up on the tennis courts that were 40' from the front door of my house I grew up with in the public park next to the house I spent from age 4-18 in. I have a ball machine, electronic stringing machine, etc. Doubles partner is the local D1 coach.
The last few years I have had a renaissance of sorts with 1980's -2000s rackets I didn't get to play with during those decades. Lately my thing has been all the various Rad OSs and really lately accumulated a few, many, more than 6, Pure Storm GTs - weighted to Tour specs. Then recently I started watching videos of Mark Vines on Youtube. That former top 200 pro who beat Lendl in '81 I believe on the way to his only tour title is killing it in USTA 65s using a fan shaped super OS racket.
I had tried some of the big OS rackets. I demoed a Big Bubba 137, have had many Ti6s with lots of lead and Blu Tack. A few monster Princes from yesteryear and many 106/107s. I got on racket finder because I don't like the 115+ rackets that are super light, super stiff and head heavy. Also most of the "super" OS rackets over 110" have 16x19 patterns and in my mind makes those things more akin to a fishing net than a tennis racket. (I have had a 93" PK Micro Mid 22x30 and even strung it twice before passing it on). Also I am no stranger to long body rackets currently having more Changs in 107 and 95" than most people have seen in a lifetime and a cornucopia of others - shhh.. anyone want a pair of Pure Control 95+'s - what was I thinking
Anyway - 18x20, 115+, RA less than 68, 11oz strung with syn grip and 1 og, 4 or 5 pts headlight, 28" or longer, comes up with 3 rackets: Wilson 5.7EB, Prince Thunderbolt and a Spalding. Picked up a trio of the Wilsons because the spec interested me and a Thunderbolt OS cause it was pretty. Strung them with multis and syngut and started launching line drives to the fence. Almost gave up because I will not use poly in these monsters. Strung up Ashaway Kevlar 16g x Ashaway Zyex 17g in the crosses at 65/58. Holy Canolli! One of my routine hitting partners told me that he might be looking for an OS now. I don't find any trouble using a 1HBH with these "banjo" rackets. My serves nearly make me pee myself with glee. Volleys require a little "trombone slide" work with the grip but not disheartening. 115" 28 or 28.5" headlight 18x20 is pretty cool to me even if the "kids" think it is "old timey" and not hip. I feel a very large racket donation coming to Goodwill - again - to clear some space on the walls for longbody OS headlight rackets.
