just go straight into a new design not based on the Sunbox layout? I'm also working on having carbon fiber plate sets made for the existing LBC jr (classic) I will post a list in a few days for those seriously interested.
I'm not 100% sure what the new base material will be but I'm considering black g10 or Ultem. I have both materials in stock but the Ultem isn't cut.
Since I already have a couple of LBC jr. (and loving 'em!) I am voting a new design
Also, have you considered making black button set? I think that would be cool for LBC200 and Jr. 200 is a beast and Jr with light-weight black covers are just right for taking them around.
Happy Holidays.
