It would be .00353 for Ti grade 2 according to Steam Engine and just as you said many have said their wire is grade 2.Hey Mactavish....since you know Ti really well, would you happen to know the tcr# for Sweet Spot 0.5?? I asked SSV and they sent me the .csv files. I used the .csv files for my dna 200's but need a number for my VTC Mini. I read somewhere that SSV wire is grade 2 so should I use 0353?? Thanx!!
