Up for sale or trade are three Wilson Hyper Pro Staff 6.1 Stretch racquets. Two are 4 1/2, and the other is 4 5/8. Two are strung with Gosen OG Sheep Micro 17 in amber and have TW leather grips (22mm x 1.3mm). The other is unstrung and has no grip on it. I can provide a gently used TW leather (22mm x 1.3mm) grip with this frame. All are well-used and in around 7/10 condition, but no cracks or structural issues. Specs can be found here: http://www.tennis-warehouse.com/REVIEWS/H61/H61Review.html I'll be glad to provide pictures and prices. If you're interested in trading, I'm interested mostly in POG OS frames and Dunlop 100, 200, or 300s (Aerogel 4D and older). Thanks for looking!
