GM1:
What size tires (wheels?) are you going to use? The 2" soft foam ones in the kit will last about one day at my field. The hardware for mounting the wheels and pants to the stock gear is like none I've ever seen before. It doesn't look like the axles are long enough to use a larger diameter tire. As the diameter increases the width of the wheel also increases and then you run out of axle length. The gear is pretty slender there at the end so drilling the hole out to use a dubro axle may not leave enough material for strength. The Icepoint landing gear that is being used as a replacement, what is it made of and how much does it cost? Is it big enough to drill out to accept an axle? Are you using the stock pants? They seem small to me. I've got larger ones on some .40 size planes. Also, they are drilled out to work with the weird Excelleron axles so would require mods to adapt to other axles.

Later,
