Kellie,
What you are experiencing is a filter that is just to small. It is doing it job, it is catching debris but the size causes it to start to drop off pretty fast.
My ? is why do you hate it? Is it because it fills and you have to go out and clean it, to finish the job? If so there is no comparison. The Dev has 2+ filter surface area to catch debris and still flow air vs smaller HF and LH filters.
Is the Dev Filter going to magically give your tm more power? NO it is not.
Many people claim it does but the truth is, nothing has been done to the tm. What most are experiencing is there tm running unrestricted....this give the impression that it has some how changed the TM, but it is just running more like no inline filter is actually on the line,..... Don't take this the wrong way, the Dev filter is just that, a filter, and it will start to drop off over time as it becomes full of debris. It just takes much, much longer to get there, and if you are doing average size homes 900-1400 sf of carpet more than likely it will go start to finish with no problems MOST of the time.
Next is are you happy with 2.0 hose? If you are than no I don't think you need to go to a 2.5 or 4 2 door setup. There is a lot of mixed reviews on 2.5 and 42dr set ups, The fact is my set up is 100' of 2" comes off my reel first then I have 2.5 cut in 25' sections.
With your set up I would keep cuff joints to minimum every cuff leaks a bit of air and the more you have the more lift is lost in those cuff joints, and you need save the lift for the wand slot. Bigger blowers can afford to let little leaks happen. I run a # 4 blower and I try and keep it as sealed as possible to give me the most suck at the wand. I hate to say it but the standard cuff and barb is still the best sealing cuff even though there a pain in the butt sometimes.
We make a big deal about cuffs and the true 2.0 flow but when they leak air....How much are you really gaining? Vacuum leaks will KILL a smaller blower, I would say a #4 or 45 is right at the point where you can just get by with a little leak but it doesn't take much for its performance to drop majorly if you do have leaks in the system.
Hope this helps. There are a lot of guys here that can give you there input.

but there is always room for improvement! I've been learning a lot on these forums, especially about the mechanical/technical aspects.
