Save time and money- just buy a Malibu Wakesetter. You will not be disappointed. Won tow boat of the year award last 9 of 11 years. We have a 1995 malibu echelon that is amazing...not too mention that it has over 800 hours with ZERO problems. My bro is one of the top wakeboards in AZ, now working at a Wakeboard camp in TX, and he's riden behind everything. For best wakes, all around, Wakesetter is his favorite.
For some background on the boats you asked:
Tige was started by a former Malibu VP- met him recently at a wedding in AZ for a friend, great guy, and a good product, but not at the level of Malibu IMO. A buddy of mine bought a 22 type i riders edition-- likes the boat, but is looking to trade it for a Malibu.
MB sports is basically the same mold as a 1994 Mastercraft 205, recently stretched. Mike Brendella (if I'm not mistaken) owns this company- or atleast started it. It was his elite line to contrast Brendella ski boats.
Sure, all of these boats are nice, but for your money, and total boat quality, I sincerely feel Malibu is the way to go. You will not be disappointed.
Others to talk to: Hardcore-Ski has a malibu on here, and MBrown I believe is thinking of Malibu Wakesetter to compliment the DCB, and I think SoCalOffshore (could be wrong) has the 23 Malibu Wakesetter LSV.
If you have any questions- feel free to PM me. Good luck in the search.
