Wouldn't want to criticize you victorzamora but when diving a Razor in the same way as the SMS75 of course they do not feel much different.
I dive an modified Razor 2 and started without owning my own tanks in Germany.
That meant mostly steel 10 Liter with a valve that is not very good at holding a bungee and only available one sided - for more than a year.
It took a long time to master, mostly because everyone told me it was impossible in the Razor.
Dove tanks with up to 6 Kilograms of negative buoyancy with it, even single tank (did not always look 'that' good, mind you)
That's why I am very outspoken in this regard: The Razor is able to carry any tank available in Europe (even HP=300Bar cylinders) and any valve available, as long as it is not to much for the divers body type (length, weight, thickness, can be anything).
btw.: my avatar is 2x 10Liter 300Bar steel tanks, if I remember correctly about 9lbs of negative buoyancy each, about 2 years ago.
Which is not meant to say you couldn't do everything in all the systems I can only do in a Razor and more probably.
A good friend of mine got the official Razor course from Steve himself. When diving in the US, he can only dive 1 type of steel tank with his Razor IF he's wearing thick exposure protection before his Razor starts becoming severely suboptimal. I'm sure you could dive more weight with it, but I highly doubt you SHOULD. It's certainly not the cleanest rig for steels. Maybe euro tanks are less negative, or your drysuit is helping. Let me put it this way, if you need lead.....you're not diving the configuration I'm talking about. Without lead, I'm often noticeably negative without a drysuit. Even with a drysuit, I'm noticeably negative at the end of a dive. You talk about adding weight, which means your exposure protection is compensating for whatever negative buoyancy those tanks have. As long as you're not diving a wetsuit to mildly deep depths with those tanks, you'll be okay. Below 60ft in a thick wetsuit, your wetsuit will compress and the Razor might start suffering.
Like I said, I like the Razor for what it was intended for.......but many people don't dive in that configuration.
