Jumpers - How good do they really have to be?

I’m in the process of upgrading my speaker cables to Analysis Plus Solo Crystal’s. I’ve never bought into the bi-wire hype and the cables that I have purchased are single wire. Currently I’m using AP Oval 9’s with some “light-gauge” Kimber jumpers that were given to me. My thought is that I should buy the Solo Crystal jumpers (synergy and all that good stuff) but since jumpers very seldom if ever come up used on A’gon I would be buying new and the price of new Solo Crystal jumpers is about what I just paid used for the Solo Crystal cables. Somehow I just cannot get that past by pea brain. I’m not aware of any way to audition jumpers so I was hoping someone could give me some guidance

My question is how good do the jumpers really have to be? Speakers are Totem Mani 2’s. Can I get away with a lower priced AP jumper; say Oval 9’s or 12’s? Are my current jumpers ok. Or should I just bite the bullet and buy the Solo Crystal jumpers?
