I finally decided to get a Vantage to add to my collection. Visited the site, chose 105 head size. Wanted 18*20 but only 16*19 available, thought oh well and went ahead. Only 70 or 76 flex available in 105!? Thats way too stiff for me. Also you can only go up to 300 grams in the 105...way too light. I sent them a polite email inquiring about the possibilities of a players OS option. Are there so few of us out there that like heavy, flexible, headlight OS frames that it's not worth their while to have even one?
