If you're interested, I picked up the pups the other Thursday and as tempting as it was to can the rest of my day and install them then, I waited till Monday.
If the 4 string is anything like the 5 (which I believe it to be), I think I can sympathise with where you're coming from with the 'brittle' sounding pups. I wouldn't say 'brittle', more a nice 'HiFi' sound but its pretty easy to get a little frustrated when its a 7am soundcheck and you're looking for a nice mellow midded-tone and you just can't quite shake the irritating elements of the high end.
The new pups are different. I found it surprisingly subtle, definitely less 'HiFi', ballsier, with a more balanced tone across the strings (the B used to suffer a bit when favoring the neck pup). I can't say its the tone you're looking for, I'm not even sure if its what I'm after but if you're looking to lose that 'brittleness' then these may do the trick without diverging too far from the tone you're probly used to.
If you're interested I picked them up for $80 each, which is like $50-60 of your monies. Installation wasn't real tough, the crazy Japanese can pack things in tight, so most of the harness had to come out just so I could see exactly what was going on. You'll also need to drill one hole per pup for the slightly different mounting arrangement.
