  1. I go by feel. If i feel 22's arent as nice as i would like them to be ill run some, same with any rope length. I really dont have a set schedule its more just whatever i feel needs work
  2. I can't believe you would think any of us might misbehave when you are looking the other way
  3. EF Honestly all ive ever done for cold water was added some wing angle JP
  4. What i am saying is that I think there very easily could be a modification made to be able to run zero off using the PP servo system on a non DBW system because due to legal agreements ZO cannot make a system for non DBW boats
  5. Boody,  I would pay attention because i would not at all be surprised to see somebody come up with a way extremely soon to use the old PP servo system with zero off. Thinking about it how hard could it be to make it work? with both systems you have the system telling the motor to speed up or slow down so would it take more than just swapping a few wires around?
  6. ski weighs less than 5 lbs in most cases, skier weighs usually 150 plus when put into proportion it really doesnt make a difference. The real difference is some of the newer materials are well designed and light so that is why a light ski may seem better
  7. TW, do you know what the plans are for that video?
  8. I read this post and had to join  This is just my 2 cents so take it for what its worth it I will start off by saying that i ski both systems regularly over this summer. I have ZO on my boat and a friend who i ski with alot has SG. My biggest issue with star gazer is that it makes assumptions (ass-u-me). My issue with it is that i am 165 lbs skiing at 36 mph and how SG works is it has a default skier weight of 180 lbs which it sets its baseline off of and the gps does almost nothing but give you a speed readout and gives you sup-par timing. So the boat gets up to speed using the baseline setting and then you have your 1 magnet start timing point which perfect pass suggest. After that timing is not true to the course because it is being run off GPS so the real question is how accurate is this timing? When the boat is taking times off literally dots in the sky which the system is able to have good times under almost any circumstance because it is not a fixed point in the course that you are timing off of. Then what happens is every time the GPS thinks that you go through a set of gates it makes an adjustment but what it does is it overcompensates for what it needs to do so that it gets good times. For example say that your 1 ball time is 1.71 (actual 1.68) the boat adjusts so that 2 ball time (4.22 actual) comes out to be 4.22 which sounds good but in reality for this to happen the boat has to go actually faster than 36 mph to make up for that. And then when you get to 3 the boat is then going to have a fast time so to get a good time at 4 the boat will have to then go below 36 mph again. The point that i am trying to make is that the speed is always changing. One of the big issues to look at also is where the speed makes its change. Currently they system tries to make that change immediately but due to what line length the skier is skiing that can really hurt the skier because any good driver knows that if you need to make an adjustment to the boat speed or path you need to know where the skier is in the course. If you make that adjustment when the skier is out at the ball it will hurt them because that is where they are most vulnerable as opposed to making that adjustment behind the boat where the skier most likely will not notice it. Now the issue here is that SG does not know where the skier is in the course. It has no way of figuring out if they are pulling or what and this cannot be a default thing. This is because where the skier is in the course highly depends on the line length. Compared to the boat a skier at 15 off is in a completely different place than a skier skiing at 38 off. For example at 38 off the boat is going thru the boat guides at just about the same time or a split second before the skier goes around the ball. At 15 off when the boat is going thru the boat guides alot of the time the skier is just coming off the second wake so if the boat makes the adjustment immediatley as it goes thru the boat guides a 15 off skier will not be as effected as a 38 off skier.  The difference between PPSG and ZO is that ZO makes adjustments compared to what the skier is doing immediately and SG is clueless until it finds that it has a time that is off and then over compensates to make the next time come out right when in reality if the time is off by .02 at 1 ball the adjustment needs to be made so that it is off by .02 the rest of the way thru the course. once again this is just my 2 cents take it for what it is worth Go Zero Off
