Replying to Difference between FT Konflict and 1st Chair

Before the flamming begins, I was fitted by a bootfitter for the 1st Chair. Felt great and was gonna buy but wanted to check around for a better deal first. I found some slightly used (2 -3 Days) 2013 FT Konflicts local for 240$ instead of the 399 plus 9% tax for the 1st chairs. I see the flext tongue is slightly less, but the tongue can always be replaced with a stiffer one. Other than that, are all the dimensions of the toe box the same? They both have the original shell and pro intu liner. Any help would be greatly appreciated.
