Thread: Switching asp budget to 4-1

Would It be a good idea,or to much work to switch the asp budget 4-2-1 header into a 4-1 by adding a 4-1 full merge?
Would it need shortened or lengthened for 4-1 specs?
Also what's the typical length of primaries and secondaries for hi-comp 2.0 4-1 headers
Just trying to get some input...
