I doubt very much there will be anything of note from Slazenger or Dunlop coming through, which saddens me.
Since being bought by SD, they have declined in terms of product output and player sponsorship. That I believe is a result of the SD theory of profit over quality.
All Dunlop have done in the past few years is turn out a few previously unsuccessful racquets with new paintjobs, with the odd exception of the R and NT lines. But with limited global availability, they are never going to be a success.
These days, I just think for most manufacturers, the pro endorsements that Wilson, Head and Babolat provide are too widespread that other manufacturers cannot cope from a marketing point of view.
You only have to look at the mens top 20 and there is 1 Prince, 2 Yonex and the rest are Head, Wilson and Babolat. That is what everyone sees when they watch tennis and if the top players use them, perception naturally is that they are the best racquets.
Sadly, the likes of Slazenger or Dunlop cannot compete with that. Other brands outside of the big 3, such as Yonex, Tecnifibre, Volkl, Pro Kennex, seems to have the commitment to continue to put out quality racquets, but Slazenger clearly do not have that financial commitment and for any company that goes that way, the decline seems to be rapid.
It's toughest for us types who want to play with the best racquet we can, but with the market shrinking, it only results in the top brands putting their prices up. A simple strategy really.....if you want a top racquet, you pay the top dollar.
