You guys bring up some interesting points on the differences between the glides. Both look to be well thought out products, and feedback like this should help both manufacturers. Please keep it coming!
I picked up a pair of Calibers for my 1 place Triton trailer. Used the LowPro Grip glides and the tracks grabbers. From what you said, I'm glad I went with the more vented model for the exposed trailer. I'll be curious to see how the paddle grabbers work with 3" tracks vs more traditional mid-west lug heights. Or, I'll be replacing them with larger/deeper traction products.
On the Calibers I used stainless steel bolts instead of screws to lock everything down. I find that screws pull out with movement and heat cycling of the glides especially as freeze/thaw occurs and wets the wood. It was a tedious job, but with the 1 place trailer we could set it up sideways in the garage. One thing I noticed is that the plastic grommets provided are junk. The directions say torque to 8 pounds, but good luck torque'ing 70+ bolts accurately. Plus, who would torque screws into soft plywood anyways? They squish down and end up grabbing the glide where the mfg wanted freedom of movement. Bottom line is these need to be a metal part, or a custom piece like SuperGlides offer. Although a separate collar and screw would be idea for those of us who want to use bolts/washers/nylock nuts.
For my enclosed trailer I went with a mix. It has quad flooring already, but that stuff gets eaten by carbides. Ramps will get SuperGlides mostly because they offer a nice aluminum metal edge option that looks clean. And, I wanted to try both vendors. Ramps will also get trax grabbers just like the 1 place. Inside, it's more traditional with the Caliber low-pro wide non-grip glides. Yes, I may fall on my behind, but I like the idea of having less encumbering flooring inside. Trax matt for the middle, and caliber makes some nice corner turn pieces. Just did a single track down the middle, and will move sleds to storage locations with ski-boots.
There is a slight width difference(Calibers are wider), so remember to measure that up as well. Especially where turns occur or pieces meet, or if you happen to have a 48" wide sled and a 37" wide sled together. I like that the Caliber guys were @ X-Games supporting our sport, and they have displays in our local snowmobile shop so you can see their products before purchasing. If you order super glides direct from website, there's quite an extra fee tacked on for import to the USA, so I got mine through a local shop and they used a distributor. (I'm probably bearing the cost one way or another) Will likely get a set of SuperClamps too, but sure wish they were metal, not plastic.
Will post more pics once it's all installed. Some of the smaller trailer attached.
