Tandem pushchair - oyster max vs b dual

[Awakeagain]

I posted recently about wanting the oyster max for when dc2 arrives later this year
I want to still be able to use by britax baby safe shr2 with my pushchair so I stuck to only a few pushchairs (otherwise I would look at others)
Does anyone have any experience with either of these (we have an oyster which I am happy with) but just wanting to know good and bad points about both really so I know what to get

The b dual is a good pushchair but now the oyster max is available the main up side of the b dual imo is price. As in it being on a very good offer is the only situation where I would get one over an oyster max.

The b dual is very wide (over 70cm with the wheel guards on) and the seats are awkward, children seem to find it hard to sit upright in. The max is under 60cm wide, the seats are taller, it's lighter to push and much lighter to lift folded.

I have used both and would definitely choose the max if money wasn't an issue. Even if that meant used vs new I would rather have a used max definitely.

I'm keeping my eyes out for a 2nd had max
I am hoping that by the time
Dc 2 is due (October) there will be a few more for sale as people will not need them (that got them when they first came out) I'd sell the oyster to put money towards the max so to speak so not too bad

Thanks, just makes the max even more appealing
