[TowerTalk] Steppir Vs TH7 stack question

[W3JK]

I currently have a TH7 stack and just found out that a 4-element Steppir
that I had placed order last year (and forgotten) is now ready for delivery.
I am enjoying the TH7 and just bought a TICring to also rotate the bottom
antenna. So the question is, will it make a big difference. I definitely
know its going to be better but do I now do away with the stack or have a
Steppir/TH7 stack or not even bother to do anything (Just keep things as it
is since I love my current setup and it's a pain to replace the TH7).

Just looking for a rational answer and not trying to offend the Steppir or
its die-hard lovers.

 

Regards,

Ken
