The 05 Transcend is a sick wake to wake board with big ups.
The speed is a little slow, but if you want it to be a little faster to take it out into the flats, then just bump the speed up a couple of miles per hour on the PP and your good to go.
The 06 Transcend is the same as the 05, but they but a speed base bottom to speed it up a bit, but same shape as the 05.
The new 07 Transcend is a mix of the old with the new, better speed, same pop and great landings. I like the fin extensions on the 07, verses the old fin setup, you can dial the board into what you like by taking off or leaving in the fin extensions. The Platinum comes with 2 sizes of extensions.
I have to say that I am riding the 07 Transcend 142cm and IMO its the best board I have ever been on, it does everything GREAT!
The 07 Transcend rides more like the Absolute then the 05 or 06 did, I just think the 07 does everything a little better, but some will disagree.
I pretty sure you can find a rider on here thats lives in your area with an 05 or 06 Transcend they will let you demo, if you were in Texas I would have one for you to demo, best of luck to you, cant go wrong with an 07 IMO.
