Well guys, I had my first ride on the MTX SE 153 yesterday. Conditions were excellent for it's maiden voyage, about 2 feet of fresh pow and some nice big drifts to play in, and play is exactly what I did. 
The first thing I noticed was how little a difference there was in the feel of length compared to my 121 RTX. Most of the time I couldn't tell that I was riding a 153. The only time I could really tell the difference, and I can only comment positively, was when I was in deep snow, and when I would come up and over big drifts. The fun factor of this sled is amazing ! Side to side carving was effortless, more than likely due to this sled having no sway bar. Once, I almost had the sled completely on it's side during a series of S turns, it was that easy to throw around ! And a few times, I lost track of my line in the powder and let off the gas, assuming I was going to need a lift out, but the sled picked up and went like I was on a groomed trail. I was totally amazed with how well this sled worked in the pow. I had the sea level adjustments made from the dealer, and the 22/40 gearing felt more than enough for me, while the clutching felt good as well. The front and rear shocks felt awesome. I'm running 80 lbs in the front, and 125 lbs in both rear shocks, and the ride was very plush yet still offering excellent bottoming resistance. I was very concerned about this, because I do sometimes land flat and harsh off jumps, but this suspension soaked it up better than expected, must be the new Float 2's in the rear. The skis handled well and kept the front floating well, still a bit of darting on the trail, but nothing serious. The only thing I am concerned about so far is the track. I had to ride over approximately 5-7 kms of trail where there was less snow, while the rest of my day was about 70% powder, and the lugs are already folding over. I'm not quite sure how bad they are compared to previous Mav tracks, as I have nothing to compare it to, but it is noticeable. I am considering cutting the lugs down to 1.75" if it gets any worse, but I'll keep an eye on it and decide after a few more runs. Overall, this sled was everything I expected and more ! I just can't wait to get out on it a few more times with even more snow to open up the potential of this animal

Glad you like it. It is an awesome platform straight from the factory. As for the gearing 20/40 seems to work much better in these sleds so keep an eye on falling rpm and backshift when there is a big load on it. With bigger riders its a bigger problem with rpm and load conditions but something to think about. Other than that hope you enjoy the sled and get a lot of miles out of it. Have fun and be safe this winter.

As far as the lugs folding, I noticed it also but they seemed to only go that far. I just got home from Cooke City, and they havent folded anymore. Hope they stay that way!! Man it is a fun sled to ride!
How do you guys like the floats ?? Front and back??

The floats make a huge difference, I tried the nextech rear float conversion and love it wish I could find a float for the rear/front. It is a little shorter too which will help!

Oh well guess I know what sled I am going to picking up for next year.
Thanks for the great report NM. I think this will be one great sled out here on the east coast.

Some pics of the sled, unfortunately, not on snow 
Notice the slight folding of the track lugs. I'm not sure if that's a lot for only 100 kms use in 70% powder conditions, but I'm going to keep a close eye on it for sure.
Installed on the sled is some White Yamaha handguards, a White Yamaha skidplate, the OFT Racing steering relocator (AWESOME) and a Lake Effect Snow 4" Black anodized riser and pivot adapter (AWESOME). I found both of these much needed steering mods were very well suited for this sled, especially for stand-up riding, yet I could still read the guage pod through the legs of the riser block while sitting down, which was pretty neat ! Next on the to-do list is the 7s battery (ready and waiting) and a Yosh pipe mod for an easy 20lb weight reduction. I'll update this thread throughout the season, stay tuned
