By the time you bought all the shit to make an R8 Ultimate truly "ultimate" you'd have another $1200-1300 in it.
If you buy a R8 professional $2100 on Euro Optics, and a GRS Bifrost for $500. You will have a better system.
The adjustable R8 professional is kind of a huge mark up for what the cost of buying a regular R8 and a GRS.
Just saying.
