I have had this on my trailer. I found that it did more damage than with carpet. Very slick for sure but took of the gel coat quicker than carpet. Liquid Rollers sprayed on the carpet works just as well and less damage. Unfortunately I have a SN 200 and there isn't a trailer out there that doesn't damage that hull.
Unfortunately Masterline is all out of right foot liners. They are the same thing as the old black ones. For now I will continue to duct tape my old black one.
I had to replace the original liner for the R Style late last season. The new one from Reflex is too thin. Does anyone have a option that is closer to the original liners? Maybe a cut down Intuition liner?
A couple years ago I started using the Masterline due to the fact that is what is used most often in tournaments. That being said, InTow makes a great rope. Use InTow handles.
Be patient. I'm sure the 2000-2010 market will come down to reality when they are not selling and they want to move onto their next boat. Three years ago I sold my mint 2009 SN196 in the high 20s, because that is what it was going for then.
With D3's demo program it is easy to find out what fits for you. They sent me the EVO S and the NRG R1 last year. After skiing on both I found the NRG clearly suits my style. For others I know that it was just the opposite. SO if you are interested try them both.
We use a Styrofoam buoy as our sub buoys that may work for you. They have not deteriorated in nearly 20 years that we have used them. We use to use a boat bumper style buoy and those lasted 10-12 years.

Higher the speed the more it is affected by small increments? Magnification. At a slower speed the movements are not effective. And by slower speeds I don't mean 30 vs. 34 or 36 mph. I mean 10 - 15 mph. I don't know I bury people for a living.
If there is a Master Craft dealer near by I would check to see if they would sell you a factory travel cover. It is a shrink wrap cover with felt inside. Did this with my Nautique a couple years ago when it got shipped up to me from Florida. Worked great.
I have a course that I use often without the 55s. You line up the right gate with the 5 ball for timing. I do have 55s that I take in and out (there is a sub buoy that I clip to) with each use when I can. As @Horton said it is a lot better with the 55s for timing. My reason for not leaving them in is the same as yours - the neighbors do not want us to extend the course any longer than it originally was installed before there were 55s.
The times I ski without the 55s are when I don't have time to put them in (5 minutes) or when it is too cold to do so.
Hopefully you can do as we did and install them and take them out when not using.
