I think the best thing to do is think about everything that bugs you about your current bag, and try to remedy that with your design... think about the way that you personally fish (ex: how many plugs you carry on average... the length of the plugs, do you use buck tails, do you carry a leader wallet, do you wetsuit, carry rigged eels or not, carry your bag on your belt or shoulder strap, etc...

Then set out to make a bag that suits your exact needs... if you end up making a bag that fits these characteristics, you will love it... it will truly be custom.

For example... one of my current bags that I use 99.9% of the time is a small 2-tube bag. I wear it on belt loops, and I swing it around my belt to access plugs and rigged eels... one issue I had with my belt loop bags before this, was that I also have my pliers and knife on my belt on the same side i slide my bag to front. so everytime I needed to access my bag, I first had to slide pliers, and knife over... THEN finally my bag. Then to fish again i was sliding: bag, then knife sheath, then plier sheath. WAY too much shuffling!

I always wanted my knife in the same exact place, and minimize gear on my belt... So i asked to have a small custom loop of webbing built into the side of my bag so my wenoka sheath attaches directly to the side of my bag...
This solved 2 of my problems: i now didnt have to slide my knife over every time i needed my bag (belt de-cluttered), and my knife is always exactly in the same place where i can blindly access it in an emergency.

Now my point is... no one except myself could have told me that this is what I should build on my bag unless they personally experienced the way that i fish and my current setup... The ideal bag and custom features should come directly from the way that YOU fish, and should make your outings more efficient and less frustrating.

I would also think about every part of your previous bags that has ever torn, worn out, etc. and reinforce the hell out of the one you build.

Not sure if these are the suggestions you had in mind, but it's what makes sense to me.

NOW... that being said, I dont think I could ever build a bag built as solid as the commando 2- tube bag that i own. It continues to exceed my high expectations after multiple seasons.
