Idea for DIY tone arm

[sleepy]

Basiclly I want some comments on an idea to get more from a tonearm.
I have bben thinking how on most tonearms the wire are fixed internally for what I assume, are cosmetic reasons.
Yet these being fixied in such a small space must be inhibiting the free movment of the tonearm bearings.
I notice that linear tracking arms usually have external wires, dressed in an arc shape in such a way as to allow free movment of the tracking arm.
How about getting a cheapish arm such as a Rega RB300 rmoving the tone arm wires completly, then fixing some allong the outside of the mains arm tube, then arching them in a loop to allow the freest movment?
I have experimented with the postioning of internal wires before and found very large performance benifits from getting the freest possible movment .
In fact one of the reasons Rega dont recomend re-wireing is because they feel many wires interfear with the free movment of their bearings.
Any thoughts, opinions ideas?
