For a while I had the boogie label 80w celestions in a full stack, they sounded so-so but I ended up switching over to 2 806 W/ the EV's and never looked back (maybe one of the few times switching to EV's saved me weight). When I was looking like you are for speakers again I just remembered how nothing sounded as clear and powerful as the EV's in my combos, in the 806's, and the 4-10's and they never let me down no matter what abuse I threw at them.
This is compared to Eminence in combos, celestion (marshall cab & boogie stack), and fender jensens, JBL, and CTS, and Hiwatt Fanes.
The jensens and fanes sound great but are kind of a one trick pony, fanes for rock and jensens for blues. Vintage jensens have trouble surviving any kind of abuse (and JBLs for that matter), and fanes are pricey and hard to find.
I think the aluminum dome and 4" voice coil on the JBL 12's are problematic in a guitar speaker, with the 15's not so much, but still not perfect or as robust as the EV equivalents.
The smaller voice coil, paper dome, power handling, efficiency, and frequency range of the 12L make it about the perfect guitar speaker. If you know you already prefer them go with your gut.
Just be glad we don't play a B3.
Of course my next build will be taking the weight to tone factor to the extreme, a twin 100W dumble walnut combo w EV's. I won't have to worry about anyone running off with that one!
Oh yeah I forgot to mention back in the punk rock days, you sure could move a lot of gear on a skateboard! I remember gigs in S.F. where you'd have to park blocks away and "riding" my gear to the clubs like a scooter. Always good to have in the trunk for breakdowns, running out of gas, to much to drink, etc.
