For sure put the original one on eBay. Get some dough back.
People buy them for various reasons, e.g. someone on here wanted one cuz the one he'd got smelled of smoke.
I saw a nice GS Mini sans case on eBay once, the guy said the case had been ruined by wet mould, having been left in the garage (while guitar was indoors).
ps. I'm with Desert Twang, I find the Taylor bag more than adequate for carriage. Front pocket holds 4 cans of beer with ease !
I realise if I fall off my bike with it, it's probably toast, especially with the beers on board. Life's full of risks. ...
