Nice job!
Dumbells are the way to go. Far more effective than the barbell... you work on all those stabilizer muscles
To give you an idea, when I do squat-cleans in my training, or thrusters, I use a barbell with either 135 lbs or 115 lbs (depending on what's prescribed for that day). When I do dumbells, I need everything I got to manage the 55 lbs dumbells (that's a 25 lb difference!). They are also awesome for balance.
The only reason I don't do more dumbell work are 1) I don't have any 2) If I did, I couldn't drop them
