Is it possible to copy a named range based on a variable?

I have a number of named ranges which I need to copy based on the
results of a cell value.

My whole routine is nearly 500 lines of code, so I've only included the
relevant bits in this message. For example, I have the following lines at
the start of my routine:

With Worksheets("Lookup")
Set MTS215Vision30 = .Range("MTS2.16Vision30")
Set MTS216Vision30 = .Range("MTS2.16Vision30")
End With

and want to copy one of these based on the value of cell which could
currently contain 2.15 or 2.16.

This line:
sMTSVer = "MTS" & Worksheets("Input").Range("T3") * 100 & "Vision30"
makes sMTSVer = MTS216Vision30

This works:
MTS216Vision30.Copy .Range("A5")
But this doesn't:
sMTSVer.Copy .Range("A5")

I know I could use something like .....
With Worksheets("Input")
If .Range("T3")=2.15 then
MTS215Vision30.Copy .Range("A5")
Elseif .Range("T3")=2.16 then
MTS216Vision30.Copy .Range("A5")
End If
End WIth
...... but in time there will be 2.17, 2.18 etc and I am hoping to "future
proof" the code so that I only need to create the named ranges and add a
"Set" line rather than having to add more If conditions, as the Vision30
example is only one of a number of similar situations.

Any ideas? I need this to work on any machine with a "default" Excel 2000
installation (ie not an add-in).
