Great memory! I still have my BB11SE's, but those are not headlight enough for me. I was thinking of removing the lead, or maybe shifting it to the handle, but alas, I haven't had the time to really tinker with them (plus I'd like to keep them in their original state for now).
Yea, never quite found the PT280 replacement. Was funny though, I had a similar experience like you, I pulled out the PT280 one day a few weeks ago and won a great 6-0 set. I still may circle all the way back to it soon enough.
Right now, I'm actually enjoying the new Prestige, YTPP. Strung with overgrip, it's right around 12.5 oz, but more HL than the PT280. The added stiffness and open pattern make it a spinnier, more powerful version of the PT280, with a touch more maneuverability, without sacrificing stability or flat-winner controllability. Not quite the feel or flex of 'ol blue or the classic prestiges, but I guess that's the trade-off.
I guess my "back to prestiges" motto was a little misleading, I'm more "back to the prestige line", except in their newer form in the YTPP. It is a nice blend of classic and modern frame tech, imho. I still also keep the Prestige Tour 600 (Mid) handy for casual hitting, but the forgiveness and free power of the YTPP's 98" in comparison is nice, especially in competitive settings.
I did remove the lead off the BB11SE, and it then becomes very manageable, around 325g unstrung I think. The racquet is still very stable and has this nice flex. I may have a spin with it again some time soon. To me this racquet plays more like a 93 than a 98, very controlled and tight string pattern, great serve placement and overall very good from anywhere on the court. I actually often think of it as a modern PT630.
