Maybe start working on those transitions and getting him to really consistently go exactly the speed you ride him. I might think of doing 90% of the work at the walk and trot - particularly in that fast walk to slow trot to fast trot and back down again until it's -real- smooth. Really, you're working for the perfection of those things. Then when you lope your horse, everything you want is already mostly there! Also, your horse can last a lot longer at the walk and trot. With loping/cantering, 10-15 mins tops and he's done whether he learned anything or not!
