Called my dealer to ask about QH's. He informed me only the QH05 will fit on my BX. I educated him about adapter bushings, and that LP website says the 5, 10 and 15 match to the BX. I don't think the sales guy is a tractor guy. Anyway, I think I'm passing on a QH, at least a land pride. $225 for the 05, and the top hook isn't adjustable. $445 for the 10 or the 15, and only the 15 is adjustable, and in stock. I can't see me spending over 400 since I"m barely a hobby farm here, most of my use is the FEL, though I have used the sprayer a few times already, and plan to do some rolling and aeration work soon. But $445? Nah, I'll just deal with the terrible turnbuckles.
