advice needed on Stellar SEI and Swordfish S - by: sv607

am thinking about upgrading and getting a Carbon Swordfish S or Stellar SEI in Carbon. i heard the Swordfish S is better in the rough water over the Stellar SEI is this because the Stellar SEI is more twitchy . i know my current swordfish drains much faster in rough water than my friends Stellar. but the stellar seemed to be a faster ski. have people who have been out on the Swordfish S i heard its got a lower hump. thus fixing the dead leg. any advice would be great..

thanks in advance
