Gecko 6 Neck

Has anyone used the Gecko 6 necks from Warmoth before? How are they? I'm considering upgrading the neck on my 6 string SX Ursa. There is no problem with the neck, in fact I find it comfortable and easy to play, it's just because I want a 35 inch scale.

How easy does the neck play, and how heavy is it compared to the rest of the instrument? Will it fit on my instrument easily, or will I have to do some kinds of repairs to get it working right?

Any advice would be appreciated. Thanks.
