If you're interested in ultimate lightness (and you're willing to pay for it) you might want to check out Interspiro. They have a range of composite (carbon fibre wound on a thermoplastic liner with epoxy coated glass fibre overlay) cylinders rated for 300 bar use. To my knowlege they're only available in 3.4 and 6.7 litre volumes, so they're probably a bit small for a twinset but I guess you could do the weight/cost sums and see if a triple/quad made sense. The 6.7 litre Spirolite weighs approx 4.7kg. You can reach Interspiro (my only connection is as an Aga FFM user) on: UK - TELFORD, SHROPSHIRE - 01952 582822 USA - BRANFORD, CT - 0203 481 38 99 SWEDEN - LIDINGO - 08-636 51 00 Regards & safe diving Paul --------------------------------------------------------------------------- | Paul Chapman EMail paul@de*.de*.co*.uk* | ---------------------------------------------------------------------------
