If you want to master nose in right now keep them on, no harm in it.

Another option is to make some intermediate gear. I stuck practice golf balls (miniature whiffle balls) on the ends of an 18 inch carbon fiber rod (from the gear you have now? ) and just attached it to the rear skid supports with wire ties. works great. still impossible to tip it over, but a lot lighter than the regular training gear. if you raise the rod just a bit off the skids the skids is what you land on but the littel balls are there to keep it from tipping if you need them.
