Zone vs circ vs Variable speed

<span style="font-size:12pt">I'm about to install a 95% condensing boiler to an existing baseboard system; 3 zones 2000 sq ft home,  135 ft of baseboard element.  One of the zones is an “old school” 1” venture loop. Boiler is a Triangle Prestige.</span>

<span style="font-size:12pt">My original plan was to use the Grundos Alpha circ and pipe using zone valves.  I’ve been getting poor feedback regarding the Alpha, so I’m re considering either a single speed 00 series or possibly 3 circs “one per zone”.</span>

<span style="font-size:12pt">What would be the best option for this type of system?</span>
