Would it be best to pilot the a unique premium crisp product to gage market appeal ?

Premium crisps are targetted at adults and it is a growing and highly competitive market - there still continues to be new entrants to this market which makes me believe that there is still scope for opportunity.  I have drafted a uniquely designed packaging and will look to source recycled/eco friendly materials from fair trade countries.  I also plan to locally sourced hand cooked crisps which can be grouped with other brands such as Kettle, Tyrells, Real etc  I also will be looking for funding streams to help launch the product and was considering in approaching EEDA regarding one of their schemes/grants.  I look forward to having my question answered.
