well, i'm not lefty so i dont really know what to play a 'reverse' guitar means (even if i'm a proud owner of a PII!), but in my opinion you're right, cause if you get used to play a righty guitar, you will never had problems finding your guitar of choice on the market, and you'll have no problems when you'll happen to borrow some friend's guitars. cause this will happen to any guitarist, sooner or later.
just get used to it, and you'll never have problems at all.
btw, dont worry about what we think about the TRS, if you like it, and if it works for you, that's fine.
