I was at my local tennis shop today and asked to have my RDS001MP strung with what I thought was Nalbandian's setup (when he used that racquet, though perhaps someone will tell me it was PJ.) Luxilon Big Banger Original at 64lbs, according to this source he still uses that on his newer RDiS100MP (again, this might be a PJ, no idea.) David Nalbandian Yonex RDiS 100 Luxilon Big Banger Original 64lbs http://www.colinthestringer.com/pros-strings/ First question, did he use this string setup and does he still?. Second point, is it a rather extreme string choice and tension combination?. The woman in the tennis shop was a bit concerned when I asked to have my racquet strung with this setup, first she rang Yonex to ask whether that frame could take that tension (I had read it could go up to 65lbs which they confirmed) then she rang the Yonex sales rep who is a good player and general tennis equipment nerd/guru apparently, I ended up speaking to him on the phone about it. He said Nalbandian probably doesn't use Big Banger original any more and probably uses either ALU Power or Roughs (apparently most players have moved towards these strings, hardly anyone uses Big Banger original anymore.) He also said Nalbandian uses a 28inch racquet (or a 28.5 can't remember) which further skewed the setup data (not sure how, what difference does it make?.) He suggested I went with Alu Roughs at 58-60lbs (I told him I use roughs in my RQiS 1 Tour and was happy with them.) He said not to go above 60lbs with the RDS001MP or it 'will feel like a plank'. I went with it in the end, and left my racquet to be strung with Roughs at 59lbs I am happy with my RQiS and the setup and want to use the RDS as a sort of experiment racquet to try strings and setups etc so I am still tempted to try the Big Banger original at 64lbs, just wondering what it feels like and if I don't like I can just get something else put in instead (as it's not my main racquet anyway.) So (sorry for long post) is what Nalbandian uses too extreme?, would I risk breaking my frame? (this was suggested in the shop today.) Basically I want to reduce the power of the RDS001MP and have something very control orientated, not bothered if it feels a bit boardy really (I don't think anyway, willing to risk it.) Glad the woman at the tennis shop took the time to research all of this and I'm sure the Yonex rep knows what he is talking about (in general) but just wanted a few second opinions.
