The idea behind low frictional losses is to use as little spring as is necessary to make the power, even an over tight guide whether in the spring or on the piston rod will rob the gun of power.
I agree with the "true" comp tube , though I haven't come across a gun yet that has suffered from low power when installing my set up, I don't bother measuring them as I haven't the kit to sort it out, my bore comparator won't go down that small. I have telescopic gauges but its a bit off a faff.
