While my first preference would be to go with V3 for the added cooling capacity, it is currently out of stock in the store. This is the last piece I need to order to start my first build so my question is: How do the V3 and V4 heat sinks stack up against one another? Is it worth waiting for the V3 to get back in stock or will the V4 work just as well. Retrofitting an old US stunt saber with a tri-Cree (R,R,RB), illuminated AV switch and a NB4.
