I haven't read thought this thread so hopefully what I'm about to say hasn't been said already.
From my perspective there's a few issues with this set, but the main problem is that there's a very good chance that, if this set got 150 orders, only the base kit would hit MOQ due to there being 2 options for modifiers. Most people will only choose one, making the effective MOQ closer to 250 (based on current order ratio) just to get 1 of the mod sets made.
I think if you wanted to try again I would suggest:
- Combining the base and green mod sets + light grey spacebars, to make 1 full kit.
- Keep the light grey mods as a seperate kit.
- Try and reduce the cost of spacebars, though I understand that this isn't up to you it just seems like a lot.
EDIT: Sorry if this sounded rude, just wanted to offer another perspective.
