For the Reservists, has traveling Space-Required worked when going on IDT?

I'm just reading up on the options available for Reservists. One of them is using Space-R in lieu of travel reimbursement. Given that reimbursement is dependent on unit-available funds, would it be a good idea to use Space-R first, and reimbursement when absolutely necessary?

Can Reservist or Guard members travel Space-A? | Spacea.net

Reserve members on the Active Status List (may train for points and/or pay and may be considered for promotion) with DD Form 2 (Reserve) identification and DD Form 1853 may fly Space-A to, from, and between Alaska, Hawaii, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the CONUS as CAT-VI. They cannot use Space-A to/from other overseas locations and dependents cannot accompany the member (even within CONUS).
