I just got a 2015 SC245 last night and it seems to have a different material for the inner part vs the outer part of the birds. I was having trouble finding the original spec page for the 2015 SC245. Just curious if this might be some sort of upgrade or if it's just BAU. I'll have to check the modcat next time I do a string change. I'll try to remember to post pics sometime, but I'm terribly forgetful.
