I've decided to go with the Manta TwinJammer w/ Axle, Hex Ratchet Block & Bracket Upgrades $2235 with the Hi Float Tire Upgrade $50 from Wind
Power Sports (
http://www.windpowersports.com/landsailers/) rather than the Blokart because, dollar for dollar the Manta Twin is:
1. Cheaper,
2. Seats two, no extra side cars to buy,
3. Cheaper,
4. Longer (thus smoother ride),
5. Wider (thus smoother ride),
6. More sail,
7. Cheaper,
8. Corey can use the money from the sale,
9. Did I mention, Cheaper
Keepin\' The Sunny Side Up & The Dirty Side Down!
