Huge respect kimchi. You are actually quite open minded and flexible to try an engineered base. The interesting point with this whole engineering debate is that every single engineer I know, already experimented the maxxer strategy beforehand, while the anti-engineered people rarely had an engineered base themselves. Therefore the latters know little about what is really going on in engineered wars. Engineers beat on kids, engineers get easy wars, engineers have automatic wins are such myths perpetuated by mostly uninformed (not misinformed) people and you will about to find out yourself, and you can make your own enlightened opinion.
First, an easy experiment is to try roster engineering, by adding a bunch of th3 to your wars. (Btw, u don't need a new device for each coc account. A android device can allow you to have several accounts). Let's see if you have a mismatch advantage consistentl'y. From what I have seen with match ups from UPH and Zoliday, I don't think so.
Then try a defenseless base. Up to th8, even th9, it should be reasonable easy and fast to upgrade. It may be hard to upgrade heroes to high levels, but up to lvl 5, it should not be that hard. If you are diligent with writing down details of your match up, you will soon see if even that one defenseless base has an impact on your war. If u war 10v or 15v, the impact can be seen.
A x.5 will take more time since you need to upgrade some defenses as well, but you will eventually see the impact, in smaller wars.
An easier and more lazy way to test? Go visit some engineered clans. It is a good learning experience as well.
Lastly, when analyzing the match ups, don't be like many noobs and analyze mirror bases only, or defenses strengths only, or only the top few bases. You need to compare the clan as a whole, including both offense strength and defense strength.
