I've owned a Stingray and a Sterling and the neck profile on the Sterling was fine, but there was dead spots (5th fret D and G); I've come across this on two other 90s models. The asymmetrical neck profile on the Stingray wasn't as comfortable IMO, due to the extra width.
I didn't realize you had to be Pro-EBMM to post on this thread. Either way, £2400 is extortionate.
