MM track extension

[M-Max]

Time for a new track on my 700MM
There is not much price difference to go longer.
The most popular seems to be 151.
Any suggestions or opinions

151 with hartman extensions, rail and tunnel is cheap, easy and works great. Don't forget to put on anti ratchet drivers while its apart and new bearings.

I guess the next question should be 2.52" or 3" pitch

3" is lighter and more $
2.52" New take offs are out there really cheap.
