TC-4 probs

Does anyone else have a prob of using hose clamps on thicker tubing on a TC-4? With thinner walled vinyl the space between the springs/knurled thumb nuts is just enough to tighten down the block. With clearflex 60 it's too thick and tightening the block down or connecting the tubing/clamps is quite frustating even when flexing it to create a little space.

I dont have a TC-4, but I know with my white water, the barbs are so close together that it is really hard to mount the clamps. I have to angle them all weird and use needle nose pliers to tighten the clamp. Can be quite a pain.
