Mine are Nylotron and very tight.... I guess you could argue they can't really be too tight and I guess less of an issue if nipped up in droop as the steel insert just rotates in the bush.

When I initially assembled, I left them too slack and found a very small amount of elongation in the hole into the cockpit due to the rod rotating.... maybe 0.5mm.... just enough to feel it.

Since then I tighten up, but me thinks maybe just a bit too tight :-)
