*Edit. Called and talked to Fadi. New supplier has been found, busy trying to move old stock first, and new webpage is still under development. Ti springs should be available in all common strokes/weights by the start of the racing season. 2 weeks?
I will say there is something in the works as a new supplier of Ti springs in the near future. At this time a company (X) is talking to a large spring producer here on the East Coast. They make everything from small to very large springs in Steel, Ti, and Carbon. As soon as I know more I will post it up.
Buyer beware, I don't think these are the same Obtainium springs of old. Pretty sure they're just getting (relatively) cheap and heavy springs made the same way ti-springs.com / sprungloaded / etc are doing. There's also a waiting time to "obtain" the spring which reaffirms that this is just a reseller that places their order after you've placed yours.
This new Obtainium.ca says the weight of a 300x3.0 is 430g. My original-recipe Obtainium 300x3.0 weighs 259g. Not sure if they made a mistake, but if not, that's terrible.
The best springs in my book are Progressive, DSP and Manitou in terms of weight for a measured stroke length. The original Obtainium company made a few very light ones as well (their 300 and 325 were ~250g).
Open to correction on this new company, but I'd double check actual weights of each spring before getting too excited.
