MRod lighter valve spring options?

[Tonykarter]

My buddy and I are installing Huma regulators, his a .177, mine is a .20 w MMHF barrel/MDS/TSS.  I have been reading threads on the other modifications needed to make this work.  One is lightening the valve spring.  I saw the Century TA-2122 conical spring on one of the threads, but they have a minimum of $40 to order, for a $1.92 spring.  Where else might I buy this spring or another spring(s) that would fit our purpose, without $40 order minimums?  What other springs should I consider?

This is what I've ordered and used. https://www.ebay.com/itm/OMNI-Spring-Kit-9-Pack-For-Spyder-Paintball-Guns-Velocity-and-Valve-Springs/191302968135?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

The black longer conical spring.  I didn't find a place to just get that one spring, though.  The end cap needs a little work to use it.

The lighter valve spring should be mated to a lighter MDS hammer, for best performance/efficiency. 

Hill sells a 6lb valve spring but believe it is unique to his valves.

The 6lb from hill is what I used in my stock mrod valve before getting a new valve.

I run a Huma reg in my .177 using a homemade ssg and stock hammer and spring for 70 shots on a fill. The ssg cost me nothing. The rifle is running 880 fps with 10.34 JSBs. Also opened up the valve outlet a little bigger it took about 5 minutes the valve is very soft aluminum.
Nothing wrong with using an MDS hammer and new springs but you don't have to.  Just saying
