Prestashop 2 crm 2 erp :: Version select

[HaCos]

Hello, I am about to start a new PS installation and my infrastructure goals would be to integrate with local CRM (Sugar) and CRM to integrate with my business ERP.

 

I have been searching around for a while trying to figure if PS satisfies our needs. What i figured so far is that in order to take the most of PS SEO i would like to use cleanurl module (only working with PS1.5.6) with layered navigation & i will need a PS to CRM connector as well, available only up to PS1.5 .

 

My dilemma is, should i go on with an older PS version (1.5.6) while at this point 1.6 is already out and stable ? 

Are there several other issues that i havent figured out so far ?

What do you suggest? 

 

Thanks,

C
