Yeah, I agree about ThroBak's consistency. I've had several sets of them without any issues, and the SLE-101s are the ones that have remained. Between Tom Holmes' pickups and ThroBaks, I haven't felt a need to look any further. Wolfe's Legends can't be beat for the price, either. I did have one set of Imperials about 10 or 11 years ago but, frankly, they just didn't do it for me. If I remember correctly, they had sort of a "hi-fi" type of high-end that just didn't sound very vintage-like to my ears. I do understand why some folks really like them, though, for they do have a certain tonal quality about them that's appealing to many.
As far as ThroBak's customer service goes, thankfully I've never had to deal with it, but I do have to admit that it would certainly put a bad taste in my mouth if a company didn't honor its lifetime warranty for a defective product.
