clemsondave Posted July 19, 2010 Share Posted July 19, 2010 There is another thread, just down from this one about the Z7 that has his and other fin settings in it. What numbers are you running now? Link to comment Share on other sites More sharing options...
Baller jdarwin Posted July 19, 2010 Baller Share Posted July 19, 2010 "Regular" Z7 - 6.870 tips / 2.500 / .740 DFT / 7 deg wingZ7 ST - 6.870 / 2.505 / .740 DFT / 7 deg wing.These are the numbers for a 68". DFT needs to be adjusted depending on size of ski. 67" is around .735 (flat head of caliper).

Baller Whiteout01 Posted July 20, 2010 Baller Share Posted July 20, 2010 I spent about two weeks on a D3 Z7 ST 67" and never touched the fin. I'm 185-190 Lbs and thought the 67" was perfect.   I found the ski was very sensitive to binding placement. Try moving the front binding forward one hole. It makes an incredible difference and never blew a tail out unless I screw up. I'm currently on a Fischer 68" Yellow and the ST was much easier to turn and significantly more efficient in the turn and the pull. I found the ST liked to be ridden neutral or even back a little. I would get up on the front of the ski 10-15' before the ball, once I felt the ski coming back under me I would set with a more rearward stance maybe 40/60 balance and the thing just ripped.  What a fanatic ski. The Fischer, like many skis is a 50/50 balance or maybe 60/40 in the pre turn and through the edge set. With the 9700 (I had one for a year) it has a lot more tail slide and the ST doesn’t do that. I also demoed a Strada 67†and found the ST much more aggressive at setting angle out of the ball but again with less tail slide. I found that the ST would gain angle even at the center of the boat, not something I was trying to do. My fin settings were the factory numbers, verified by Paul at D3 and I use Older O’Brien Contact High Wraps. I hope that helps.   Link to comment Share on other sites More sharing options...

Baller Whiteout01 Posted July 21, 2010 Baller Share Posted July 21, 2010 I 185-192lbs, 5'7" running old man 34.6 MPH 55KM behind 99 and 2003 Nautique with Perfectas. Typically run one 22, two 28, two or three 32 and then a 35 getting 2-6 balls depending on the day. The only reason I didn't buy the ST was I didn't gain any buoys. I think the ST is easier to ski on and significantly more efficient on the water. It rolled over on edge with much less effort, it needed to carry a little more speed around the ball in order not to over turn. It also did not hit you nearly as hard coming out of the ball. Good Luck.

icewebdan Posted July 22, 2010 Author Share Posted July 22, 2010 Did go better this morning with new number...28 off but at 54KPH (Stargaze practice)Loosing angle on offside turnNow I will try binding placement one hole front Thanks Link to comment Share on other sites More sharing options...
Baller Whiteout01 Posted July 22, 2010 Baller Share Posted July 22, 2010 You may find after moving the bindings forward the ST may feel a little squirrely when crossing the wakes.  It only took me a few passes and it completely settled down, I never noticed it again. If you’re still not able to get it to turn on you on side I would try moving the rear only binding back one hole. It always amazes me what a little binding movement can do.   Link to comment Share on other sites More sharing options...
