I do not recomend using Vmini on any approach even if it is stated in the limitation as a minimum IFR speed. Read Pans-Ops. and you will be enlightened.
Using Vtoss or 50 kts LDP on an ARA approach at MAP 0.75 NM is asking for trouble in any OEI situations and I sincerely hope your instructors do not teach that? Of course you can do it, but try it in 50-60 kts wind. How stable is your aircraft then. Always think worst case scenario, not what the aircraft is capable of doing.
Good luck.
