Would you mind posting back once you get to test out the Meelec Triflanges on the B2? I suspect they might not fit, as the tips appear to have a rather large bore from the pictures on the meelec site. I can't seem to find a local retailer that sells just the tips and the online prices for international shipping to asia is a bit nuts.
And since I'm posting, might as well ask if anyone knows if the stock B2 tips are shure clones? Looks like it from the pics available. Darn things are a bit too stiff and I'm looking to replace them with the grey flex.
