OK so I took ProNo1-252 on my business trip where I did not play competitive singles but we did a group drills (typical doubles attacking defense drills) and I also hit with the ball machine the day before so I got a pretty good feel for the racquet...I had Blade 18x20 as well with me to compare.
252 is unmodified and strung with Big Hitter Blue 17 Mains at 55 and Babolat Synth Gut 17 57. Only one tourna grip over stock 3/8 grip which I find perfect size for me and on par with Babolat 3/8 and wilson. If I remember correctly it came up to 328 grams 12 7/8 inch balance ready to play.
For those that never held one as I have posted before its like Aeropro and Volk pb mid 10 had a baby, (Although ProNo1 mold predates both of those
).
If you just look at the racquet head with white stripes glossy paint it will definitely remind one of Babolat drive series and you might assume its stiff and hollow. But when I hit with it my immediate thought was how come Babolat cannot make them like this...I know Babolat likes to make them stiffer but I am sure they don't want to make it hollow, maybe they can reach out to Pacific for some t
That unique plush flexible feel is what separates this racquet from most, maybe only volkl PB mid 10 had similar feel.
Groundies: Racquet felt good on groundstrokes if not a little underpowered but that was expected from soft relatively low sw (tw reported 315). Had better than average spin and I could do Nadal forehands or flat shots with it so the string bed grabbed well and had great control. I needed slight adjustment for both forehand and more so for my backhand but nothing drastic I could not quickly adjust.
Volley/Feel: This is where this racquet really performed. Feel is absolutely amazing and although I am not a doubles player I felt that I can direct volleys very well. Its pretty maneuverable for not being extremely head light, this is where light weight rackets help.
Serve: Did not hit any serves under pressure (competitive) just practice but it served just fine nothing impressive but nothing bad. Its hard for me to judge since I am a type of person that can serve much better under pressure (adrenaline) so I won't be able to really tell till I play competitive.
Overall: Im little bit on the fence here. Last few years I moved away from soft racquets (pt630) as I went lighter in weight but this racquet really is calling me to go back. I am however concerned about not having enough pop for light racquet that is also flexible. For example my Vcore XI98 at same specs (305r 315 sw) had lots more pop (it is way stiffer at 69). Blade on the other hand is similar in specs but had more pop with 330 sw but was less maneuverable.
One thing that confused me is twU measured specs:
Pacific
X Force Pro No. 1 144 64 316
vs
Wilson
Blade 98 (18x20 ) (2015) 140 64 322
2015 Blade although awesome and plush still felt stiffer of the two so I agree with OP that this racquet feels like 58-60. I guess we cannot go by measurements for certain racquets. I have experienced that before with 95d that felt stiffer than what TW measured and 315LTD that felt softer than what TW measured.
PS Sorry about spelling Safari is autocorrecting me all the time fighting my tennis jargon and I am definitely not a writter
