Thanks for sharing - these new 6.1s, are they 18x20 or 16x18? What brand of syn. gut are you using?I played the 6.1 Classics for a number of years and those rank among my all-time greats for serve and volley work. I really loved those frames strung with 17 ga. syn. gut, but I eventually got into some softer gear and that gave me better control that I needed around the baseline.
The Volkl C10 was an immediate keeper for me as soon as I found one 2nd hand in the classifieds here. Similar big power along with a lot more baseline control, but this racquet has never given me a lot of easy spin. Turning the ball takes a rather deliberate effort. I've stuck with 17 ga. syn. gut in most of my racquets, including these Volkls, and I even prefer its overall feel and performance over various poly hybrids I've tried - I string at home, so it's been easy to experiment.
I also added the Volkl O10 325g to my bag and these also seem the most dialed in for me with a snug set of 17 ga. syn. gut. Much easier access to spin with these frames, but just a little less top end power. Both Volkls are 98" frames with 16x19 patterns and my O10's are customized to a weight and balance that's more similar to my C10's.
My most recent acquisition has been a set of three of the Six.One 95 frames from the most recent generation with parallel drilling. These are a little lighter than my old 6.1 Classics and I'm getting a little more control with these frames, maybe because they don't overpower the ball quite as much as those stiff and hefty Classics that could be a little hot and unpredictable.
I've only been experimenting with one of these newer Wilsons strung with 17 ga. syn. gut at 56 lbs., but I'm going to string another one - either the same or maybe with 16 ga. syn. gut - for some further noodling. Although these latest Six.Ones are lighter than even the Volkls I've been using in recent years, they're stable enough to feel as though they command the ball pretty well. The slightly smaller hoop doesn't seem to diminish the racquet's inherent liveliness compared to my 98" Volkls when I practice serves and both control and spin seem to be more than ample.
