So, this brings me to my last problem. My Dolphin (as is) will not take me where I want to go. That is a real issue for me. I've looked at the Buddy systems and the Megladon. I'm not sure that the Buddy syetems will take me deep, but the Meg will. Anyone seen a comparison of the Meg and MK?
How 'deep' do you want to go?
For theory behind SCR trimix have a look at

On nitrox the depth limit for the Dolph is 40m no matter which gas and jet combination you use.
Bear in mind I haven't had the chance to trimix my Dolph yet.
