Ibanez has enough bass lines to please just about any type of player. Ok, many ppl like the SR/SRX/EDB lines because of the fast thin necks, but then there's also the BTB, ATK, and so on - those basses have beefier and wider necks, more body weight, etc. So if you don't like the "toyish" feel of a SR (for the record, I love 'em, SRs & EDBs are my favs), Ibby might still have a bass to your liking.
To me all these complaints about Ibbys are silly
Test first, then talk
Especially considering the recent models...I mean take the SRT900DX: if that bass sounds "thin" to you, then you've got a problem - 'cause that beast sounds VERY CLOSE to my Thumb BO - at half the price
Not to mention the SR500 - everytime I hear someone saying that bass sounds "thin" I can't keep myself from smiling; that bass has such an aggressive tone with a roaring bottom end and in your face mids! Every note kicks you in the chest like a rabbid mule, while the tone remains focused and clear..so I don't know what some folks are playing this bass through...that is not a "shy" sounding bass 
To me the best thing about Ibbys is how well and comfortable they feel - the ergonomics and the playability of these basses is fenomenal
I've been in the W boat for the last 2 years or so, but I'm about to switch back to Ibbys - for some (strange) reason, Ibbys just feel right
