New Regulator

[Shooter]

+ 1. I have both apeks xtx 200( which I currently dive) and scuba pro G250's which I dove for my first 5years of diving and still use. Scuba pros are not "cold water" regs, but I never had any issues with them on approx 50+ ice dives and deep dives to 150 in superior. They are both adjustable regs, which is a feature I have grown accustomed to.
Instead of using a separate octo, I will have 2 main regs with my octo being on a necklace and my primary on a long hose in a NAUI technical configuration. If I am on a dive trip and I have any issues with my primary reg, its an easy switch and I'm back diving. It also extends my service time on them. When one is getting in need of a tuneup, I will switch it to my octo and dive,dive,dive  8)
