Checking the pictures of your flywheel and clutch components, there are a lot of heat spots for only 100 miles. That tends to lean towards your clutch not fully releasing or you ride the clutch a lot to get moving. I would doubt with a 6 speed you need to ride the clutch?!
I doubt this is in the transmission issue since up shifting is fine. Hopefully this will ease your mind a bit.
Downshifting a transmission is harder than upshifting one, as you downshift, each mainshaft gear is spinning faster than the higher selected gear you shifted down from. That is why you can easily shift 1-2-3-6 but you need to slow your vehicle speed down if you want to shift 6-3-2-1.
What ever you do, you need to resolve this before you ruin your expensive clutch and your Rockzilla. Maybe an engineered hydrauilic kit might save you some money.
Those heat spots may now cause clutch chatter once your other issues are resovled.
