Yes you will need to do something as the SLU will be at a disadvantage when playing the TBU game. This is why it is so important to have a set of standards. If you get 6 different versions of IR with no standards between them this will become a real mess, and actually start dividing the hobby into their own camps, and this hobby isn't big enough for that.
Now if Tamiya guys adopt the cone reflector to do away wiht the 45 degree defence that would go along way to setting the systems on a level playing field.. The big question is will a crtical mass of Tamiya tankers consider this a necessary thing to do????.
I always find the discussion of TBU vs other unshielded XBU's interesting. If the TBU is the standard, and i do see that, then someone, using something more sensitive, just needs to be aware of that and accept that fact, no biggy, and should not disrupt the play nor be eliminated from the competition.
We have mixed "XBU" at many of Kelly's Heroe's meetings and it never even gets any discussion. If something else was the standard, say el-mod, then the TBU "might" be the unit that everyone would consider harder to knock out. Make sense?
