Stan - That is quite interesting looking! Almost like some cluster blooms that open up starting from bottom to top! Neat!
I have come to the conclusion here that a "good" bud builder is a scape that not only has lots of buds, but many branches, too, so that the blooms don't get hung up on each other as they bloom and wilt. I think yours would be a scape with lots of buds, not necessarily a bud builder - if you know what I mean.
