What's the problem with the MCFK post and your current saddle?
I use AX Lightness Daedalus on my MTB but that's about the price of the MCFK.
My cheap setback setup is a Thomson Masterpiece setback with Ti bolts/washers, carbon cradle (Ax lightness 14g or Smud 7g) and POP yokes.
Sub 140g for my version with 300mm length * 31.6.
That's a cheap option but you won't lose that much weight.
Carbo EL is non set-back?
the issue is that the front "yoke" that secures the saddle on the post is too far forward and hits right at the front bend in my saddle's rails. it is, unfortunately, not a position that works.
i do not wish to change my saddle. if i needed 5-10mm less setback, it would probably be fine. unfortunately, that won't work.
i could go with the MCFK setback version...possibly. problem is in obtaining one in the next 2-3 weeks. how much does the AX post weigh?
i have had bad experiences riding my MTB with a thomson post and those POP yokes. the yokes failed during a MTB race. that wasn't fun--had to ride the last half without a saddle. i won't use the POP yokes again, personally...even if it was a rare occurrence.
i'm comfortable using the MCFK stuff as i know it is very light but it is also reasonably sturdy. i don't want to have to worry something will fail.
thank you for the suggestions. i'll look into the AX.
