I am an expert on few sticks but when it comes to Fischers I am clueless. does anyone know the difference between those two sticks and how do they play? History of these two sticks will help. I only know the first Pro classic 98 was part of the Bosworth collection. It does have vacuum technology so technically it can be called vacuum? not sure http://www.tennis-warehouse.com/descpageRCBOS-BWFPC.html A classic Fischer player's racquet with a ceramic & graphite construction. Offers excellent feel and control. The beam with Vacuum Technology was designed to offer an uniform response and enough feedback for the feel and touch required by elite level players. The Classic Pro 98 was used on the tour by pro player Andre Medvedev circa 1998. In other words TW states that it does have vacuum technology and can be called vacuum? am I wrong? Is it safe to describe "Fischer Vacuum Pro Classic 98, blue frame. big brother to Fischer VacPro 90, with same bumper guard to this frame"? using the word Vacuum? this is very important?for this below? how accurate is my description? and how does it differ from this frame vacuum 98 frame? Hessam was kind enough to send these two beautiful photos to me so any info welcome are the two frames above VT ceramic and differ only by cosmetic,paint job ? I was finally able to open up the original link where Hessam sent me a photo saying that this is what he was looking for only in 98 so which one is it? which of the above two frames are close to the the 90 pictured above? This fischer mombo jumbo from 10 plus years ago is so F up. I doubt many or any will know what hell I am asking or even know what the F--- I am talking about.
