I would absolutely be in for 1, possibly 3, but these baby fuel tanks have got to go..if WD can make a composite tank that holds 5-6 gal that accomidates a very similarly sized pipe(which all fits in a SJ hull), than I'm guessin that Malone should surely be able to also make/sell a similar tank for an additional option for those of us who wish to ride for more than 20min..I used to run an XFT battery/tank unit and it was awsome for balance/rolls/backy's ect.. but with 44's or 48's my ride time was right arount 20min and where I live/ride you have to pull your ski out of the lake, drive 1000ft away to a *refueling area*, get back in line with all the other boaters and relaunch...BIG FUN:banghead:
