The Commando Smooth, SA Spey Lite's, Rio's trout are really good and SA and Rio scandi's are great short scandi tapers for little spey/switch rods. I'm going to add the Wulff Ambush short. Have the 225 grain on a Meiser 10' 2 wt, Hydrogen 2 wt & an Echo SR 10' 6" 3 wt. and I love it. Check it out. Can't go wrong with any of these when the grains match your rod.
SA Spey Lite Scandi, Snowbee Switch, and my favorite, AirFlo Spey/Switch are lines that I have tried in the 210 to 250 grain range with short, light weight polyleaders but no heavy sink tips.
The Rio Single hand spey is a nice line albeit just a bit clunky.
Not your exact rod but on my Loomis IMX Pro Short Spey 5wt, I've tried the Spey Lite 360gr. integrated (OK) but I found a discounted 360 gr. Airflo Skagit Scout head that I really like. Not a fan of the OPST Commando head on this rod.
