Anyone ever experiment with 11 series weights?

There are a lot of really poor running Pro's on the snow, I rode with several last weekend, they have trouble getting out of their own way. Unfortunately a lot of folks don't have the desire or mechanical ability to improve on a bad set-up. Personally I feel every Polaris dealer in the west should be slapped up along side of the head for letting a Pro out of the shop with 10-62's if they know it will be run at elevation. Polaris has made it so simple to make these sleds perform spectacular, all you need to do is run Polaris "book" set-up for your elevation and you will run with or better than any NA 800 on the snow.
On my 13, when new,would pull 8100 . At about 225 miles it gained rpm to 8250-8350 and didn't feel like it had the same seat of the pants pull, but still good.(I know not scientific) Sounded high for my liking too. Took it to the dealer and they couldn't find a problem, cleaned the clutches and belt and the next ride was at 8250 all day.Ride at 4 - 5500ft. Am going to put 10-66 weights in for next season to get it down to 8000 - 8100 range, I think it pulls better there IMOP. Have seen posts saying the torque peaks at the lower rpm. Have also seen some posts of other sled gaining rpm from new, at low mileage,is it from break in? Just have to fine tune to your liking.
I thought I'd throw in a tidbit of springtime tuning knowledge gained over the last few weeks for those who may be planning a spring ride. With summer coming and riding temps approaching 50-65 deg. the snow has become slush with extreme shear and very little resistance/backshift. Myself and most all the people I frequently ride with are losing RPM's (200 to 400r's) and having variable tuning issues. The cure for my Pro was dropping my primary weight from 60 grams to 58.5 and run the higher rate 160/240 black purple in the secondary with two delrins. Riding temperatures lately have approached 65 deg. and riding elevations have been 9,500 to 11,200. The sled performed nearly flawlessly pulling 7950 to 8050 RPM from morning until quitting time. We played "King of the hill or King of the pull" like usual all day long and with the tune up the Pro was very dominant. Polaris "textbook recommendations" are proving to be very difficult to improve on. I'm looking forward to another month of fun as a storm is brewing on the horizon. 800 miles of WOT mountain climbing on the new sled in the last six weeks with out any QD belt drive belt issues.
