What do you guys think of the lightest 68/45 tank made by inocom the CP cylinder with arguably the best and almost lightest reg the Ninja Ultralite can the reg screw in the tank would this be the almost lightest 68/45 with the best reg?
Best combo I've used is the Macdev pushbutton legionair system. It's balanced more then anything so I don't even notice the weight of the reg on marker.
That's what's really more important then anything, balancing your setup as that takes the feeling of 'weight' off your hand.
Best is very subjective at times, especially in this since you're looking at weight and performance.
For me, performance is always number one and weight honestly not even a thought. It's different for other people though. That being said though everybody is going to have their opinion on what is the 'best' combination.
If you want a ninja, get a ninja. If you're looking at GA have you considered purchasing just the GA cylinder and installing an ultralite ninja reg?
