Question on springs: What is a "good" mainspring?

Hi all, newbie question again . I'm in the process of changing my TX200 mainspring. I bought it 2nd hand and I'm doing a change on springs, guides, seals, o-rings, etc. For now I'm going with a factory one. But, I' wondering, what makes a mainspring a "good" one. What makes an aftermarket ...

Looking for Tx200 mk3 stock

Hi
I'm looking for a cheapo stock for Tx200 mk3. The main objective is to practice cutting it.. so it must be as cheap as possible :)

Im in Portugal so also need to take into account the shipping costs.

Tks!
