onto new news (geddit?) i bought silicone tubing for 25 aus 3 metres with stainless steel spring in it
what im thinking is, that spring is absurdley restrictive.. so im just gonna take it out and hope the tubing wont collapse on itself

If it's a pressure line (on the pump output side) collapsing won't be a problem. More of an issue is whether or not you are likely to get a kink in it, but that can be avoided by careful routing. I have seen some folks avoid kinks by putting the spring on the OUTSIDE of the tube to give it some support.
Even if the line is a suction line, (typically either the last block or res -> pump) it's unlikely to be a collapse problem unless the hose is really flexible, our pumps generally don't pull enough pressure, especially if you paid attention to Phaestus' article on getting net positive suction head, and designed your setup accordingly.
