Adding T track to the mast for main sail?

We have decided to order a new mainsail to our boat.
And now we are discussing different solutions for mainsail arrangements.
We have decided to go for a fully batten main, but we have been discussing three different options for attaching the sail to the mast.

To keep the existing configuration with Rutgerson battcars running in the existing groove in the mast using nylon slugs for the intermediate points.
The battcars look like this.

Same as above but use cars for the intermediate also, like this
Added cost approximately 500 USD (compared to 1)
Give less friction than 1.

With alternative 1 and 2 the T shaped piece going into the mast groove can jam when they are exposed to side forces.

Mount an outside track on the mast and use battcars and intermediate cars designed for this track.
This is the system Iím looking at
Added cost approximately 2000 USD (compared to 1)
Less friction than 2, especially when there is side forces on the car

The boat is 38 feet with a mainsail of 36 sq m

Does anyone have any experience doing changes like this?

Try for a ball-bearing system battcar system; but be prepared for the sticker-shock

Here's the system I used with my new full batten mainsail. Works excellently and has no ball bearings.
