Marshals m joint a good idea ? - Is it a good idea for a 35sqm patio

[pop]

Hi I am planning a 35sqm patio using indian sandstone, I am trying to work out if it is best to use mortar or marshals m joint for pointing.
Does anyone have advice or experience they could pass on would much appreciate any comments.
Whilst asking is it also okay to lay slabs bevel side down?
Cheers Pop

I'm still waiting to try it for myself, along with the new Bradstone Jointing Jollop that was promised to me weeks ago.

However, having spoken to half-a-dozen contractors that have tried the M-Joint, two were happy with it, three reckon it is not as good as Romex, and one said it was a pile of ... something or other.

Until I get a chance to blag a sample from someone and try it for myself, I'll reserve judgement.
