IF you found what you like why not stick with it? Riding indoors is not the same as riding outdoors. Wait to get this setup outside and then decide if you are lacking anything. If you are just trying to save 100g on a saddle, IMHO not worth it. Also the 3D printed saddles are NOT for everyone.
Having said that, I have that Elite copy of SLR and it measures and fits like my original non 3D printed SLR. However, the 3D print is very rough and if you shift a lot on the saddle, your bibs will take a beating.
