I tried the 8-10-12-14-16.   I like the 14#.

That’s surprising figured the lighter spring would feel flatter like in a 2011

I had feeding problems occur when I went down to 10 lbs on my Primary slide. No issue with 11 or 12. I use the former.

I’d go with the 11# spring. That’s what I currently have in my Shadow 2 and it shoots flat. My load is 124 Gr PD JHP at about 130-132 PF.

11 on mine, SRO for optic , our own 147 reloads minor (130pf), shoots pretty flat. I had a Vortex Venom on their before, I'm not noticing any difference in

slide movement or tracking

CZ shadow 2  Cary optics.  CZ custom did the slide Lightning  delta point pro, using 11 pound recoil spring.  147 grain bullets 3.1 g of titegroup 132 power factor.  Zero issues of the last 5000 routes.

Had CZC do the slide cuts and plate system w/ DDP but now have the SRO. Had 11lb but started get light strikes.  I shoot factory ammo, typically 124g or 147.  Went to the 13 lb and no issues.  Personally I like how the 124/147 returns to zero, not chasing the “flat” shooting gun but that’s just me.

Using 10lb with DPP, 147 gr /130 PF loads. Like it better than the 11lb, the 10lb to me shoots slightly flatter.

I've ran an 11lb in my S2 for several thousand rounds. No problems with OEM ammo or handloads around 130PF. 

My buddy Ethan H. #6 on the Carry Optics USPSA charts shoots an sp-01 Tactical(a little shorter) used an 11lb spring with no issues and recommended that for the S2 as well.
