Sliding wardrobe doors

Hi folks,

Long-time lurker, first-time poster.

I'm building some built-in wardrobe sliding doors -- four doors at ~2200x800mm each across a 3m span floor-to-ceiling, with carpet underneath. Importantly, they're going to be wrapped in fabric so couldn't care less about paintability. I don't want them bowed though!

Searched for a few threads, looks like the wisdom is:
* use minimum 18mm MDF
* use moisture-resistant for added stiffness
* make sure both sides are treated evenly (doesn't apply in my case, unless light spray-glue counts?)
* using top-hung fittings to prevent bowing
* top-hung track needs to be perfectly level or the doors end up wonky
* you can use the Hafele Planofit straightening system to fix bowed doors

Current fittings option one:
* bottom hung

Current fittings option two:
* but the bottom guides are crap, I really need a full-length low-profile guide.
* so merge in for the bottom half.

Seems to work out to approx £120-£140 for fittings & ~£80 for doors either way.

1. MR-MDF doors will work out to around 18kg each. Are these actually likely to bow when bottom-hung?
2. Would using OSB/chipboard/ply be less likely to bow than MDF? Since I'm wrapping it anyway...
3. Nothing else in this house is straight, so I expect the ceiling/opening won't be either, and I need to check it's on a joist (I think it is) or add bracing. Bottom hung seems simpler to me overall.
4. If I go with bottom-hung, should I add the straightening up front? Adding it will entail figuring out how to cut a long groove down the back...
5. Am I overthinking all this? Probably!

12mm ply with a 20mm baton to stiffen and prevent bowing would give a 32mm fairly rigid door [my shop bought sliding doors are around the same dimensions ] bottom hung? think you mean to sit weight on bottom track?, this provided floor is not too out of level is the easier option. The track system allows for up to around 20mm out of level.
Thanks foxhole,

So would you put 2x vertical batons near the edges of the doors with the runners screwed through them? Just straight bits of pine or something different?

Bottom hung: yeah, sorry - I meant with the weight on the bottom rollers
