Anything over 27" please - and thanks Automatix!
Ouch... that's a long list. I'll probably skip some due to memory failure but here we go.
I'll start from the Prince Graphite Longbody since this is the frame we'd like to see again. Owned for a couple of weeks before selling it back to the original owner (he sold it, but after a while begged me to sell it back to him).
Very headlight, little to none mass in the hoop, soft but not a noodle.
Good access to spin, a bit tougher to handle when going for a flat shot. With some tweaking I could see switching to this racquet. However back then I preferred 18x20 stringpattern frames so after I got an opportunity to sell it for the same price I bought it I didn't really think of buying a new one and playing with lead and silicone to alter it to my liking.
Another frame that I remember was the Head i.Prestige Mid XL (27.75 inches long). One of those racquets which were just too demanding for me. While it was a true blast to serve with this baby I just couldn't hit a clean backhand to save my life. I thought it's a matter of time and adjustment but it wasn't... but I still remember what a joy it was to rip a nice flat one down the T with it.
Around the time I've started to appreciate open string pattern racquets I've been playing with Kneissl Red Stars aka yellow stripe (ca 2007 edition, 27.5 inches long). They were fantastic frames. Quality finish, sturdy, powerful and very comfortable. The problem was I couldn't time them as much as I wanted to. They were very string sensitive and really shined with the factory string (Kneissl Polytech). They were simply marvellous when playing in defence from the baseline however I couldn't transit from defence to offence if you know what I mean.
Wilson ProStaff Classic 6.1 Stretch 95 (28 inches long). A stiffer, crisper, classic Wilson Pro Staff feel. Also very powerful frames despite the 18x20 string pattern. Bought them as an alternative to my Yonex Pro RD 70 Long 95s (saving them for last). Never could find the groove with these also while I didn't find them uncomfortable (68RA or something in the upper 60s) I'm not really a fan of the ol' Wilson feel. I prefer the softer, smother response of Prestige like frames.
A recent talk about Babolat racquets reminded me of a very brief encounter with a Babolat Pure Control Zylon Plus (27,5 inches long). It was a very, very short hit and I've never owned one but this model really impressed me. For the weight it was plenty stable, it had easy access to power and spin without sacrificing control. I have to say that in this "weight class" it was the best +0.5inch or longer racquet I've hit with. It outperformed the Red Star in terms of spin and control, it was also more manoeuvrable.
And last but not least my current frames - Yonex Pro RD 70 Long 95 (28 inches long). I haven't seen anything which would be even slightly similar to this model. This frame screams specific. 16-19mm beam (16mm at the tip), a 16x17 (no typo, 17 crosses) in a 95 square inch size head. What can I say, this racquet is a spin monster. The fewer crosses:mains ratio design is something which can be treated as a prelude to the Wilson Spin Effect (16x15 string pattern) and the Prince ESP (16x16 string pattern). And it really works. Great feel, ball pocketing, not power deficient but you really have to give it all to achieve decent depth on your shots. This frame is like a scalpel however it is unstable at the hoop, while it is a common problem with headlight 28 inch long racquets in this model the beam design (taper down up to the tip) enhances the problem. Although it is supposed to have some "tech" called anti-twist cross section in the hoop it doesn't really help. It can be easily fixed with some lead ranging from 10 to 2 o'clock however this increases the already high swingweight and shifts the balance towards the head. I love this model even with the weaknesses mentioned and the fact it is by far too demanding for me... but heck, I play for fun not for "glory".
I've played with and owned many more extended length frames including pro stocks but the above come to mind when I reminiscent my younger tennis days.
