I was lazy from the get go. although I started when I was 33, now 40. I had dreams of a big stack. I had a fairly powerfull rack, 4 space with 1200w. my heaviest cab was about 55Lbs. right around that time I injured my back, jet ski accident. actually the 55 Lbs cab agrivated my injury.
Since then I've been downsizing everytime I find something lighter that sounded good to me. first I lost the rack and went to a head, actually it was my rediscovery of my love of Eden sound. I looked at some wt300s, 400s and even some of the SS heads WT405 and 330. then I decided on the wt550. seemed to have just enough power and "lighness" at 20 Lbs. I've never racked it to save weight, I got the eden bag. I've also tried the Thunderfunk 550, 16.5 Lbs, just weighed it. I thought it might sound similar to eden because of the control layou, but its more a SS/HIFI sound, good but different. You might also look into Aguilar ag500 heads, about 15 Lbs at 500w into 4 ohms. but if you need a heavy authoritative sound I'd look into eden first.
I've mainly stuck to 12's for my sound. 10's aren't big enough in a modular setup. i.e. I won't use a 210 cab because it would be too heavy for me to move. and I would need too many single 10s to make a loud volume. The 12's I've liked are Aguilar GS112 (42 Lbs, 39 on the NT version). Bergantino Ht112 and ex112 (39 and 36 Lbs) I've tried but don't own Epifani UL112 (30 Lbs) If I had the dough I'd get a pair of these, but at $600 each thats TWICE the price of the Aguilars.
Also look into a good two wheeler or a luggage cart. I own a Remin "kart-a-bag" tri-kart 800. it holds 300 lbs and is nice if you have a ways too walk and minimal stairs.
Good Luck!!
