Ok, I'm convinced. I'm having the tanks doubled with 200 din and an isolation valve. They will be O2 clean and filled with EANX32 for the first fill. I plan on practicing within the NDL table limits to get accustomed to using doubles and one day hopefully continuing my training into wreck and/or cavern diving. The cost of The O2 clean and fill is insignificant however just as in technical diving... every detail counts and why wast any effort/money on something unnecessary? I am going for it. Can hardly wait to try it out.
One last question. Without taking an extremely involved and expensive intro to tech course (which I am not presently prepared for), is there a basic introduction to doubles class available? I have read quite alot about setting up and using doubles but would sure like some instruction. I don't currently dive with anyone who uses doubles. A quarry near me (Mermet Springs) is trying to get SSI to sanction one but is as of yet unsuccessful.
Thanks to all for your input. Diving and scuba board are my top two passions.
