Yeah I actually went there a week before the LB was released

I was checking out the solid tube ones, I ALMOST walked away with one but just managed to resist, maybe lucky, if the LB was there I probably wouldn't have walked out empty handed

...
The thing that got me was how much difference in actual size there is between the 10 and the 12, it's quite significant, more then I thought from the specs and photos... Seems like a considerably bigger difference then between the 8 and the 10, probably because of the 8 being f6 and the 10 and 12 both being f5 i guess.. I imagine it's similar for the LBs yeah? If that's the case then maybe the 10 really is the way to go, the price difference isn't insignificant too...
As for the spoiling, it's sometimes a fine line between "spoil" and "nurture a healthy interest", in this case I think you're definitely on the right track
