Agreed, so let's look at what people expect, because 9/10 that's what they buy. A ST or TL normally leaves the factory in alder or swamp. An LP, SG, XP or Jnr leaves the factory in mahogany. If I was a punter educated by ads and guitar heroes, I wouldn't look at a mahogany TL, or an alder LP.
OTOH, if I knew my stuff, I would also know things like Satrianis are basswood, Vais are either basswood or alder, and some other top-shelf I-brand models like the Paul Gilbert and Iceman are mahogany.
So if I was listing new models, the wood upgrades would be
[*]F-brand model options as swamp ash or alder and [*]G-brands as mahogany
because no matter how good the alternatives are, people expect those woods in these models.
Assuming the only I-brand model I offer is a JEM, I would stick with basswood only and watch and wait. If I expanded the I-brand range, I'd go the Iceman/Paul Gilbert (which is an inverted iceman) in mahogany, and a JS in basswood.
